	pass once again:
	* testsuite/mac-mf.sed: Append this, s/ $//,
	to eliminate trailing spaces in the actual output.
	* testsuite/y-newline.good: Manually remove a trailing
	space between two concatenated prompts.

	not y-NUL.* here.

	maint: correct failing "version" test
	* configure.ac (COPYRIGHT_YEAR): Update to 2014, so
	the "version" test passes once again.
	* doc/sed.1: Also commit this auto-generated-yet-VC'd file.

2014-09-04  Jim Meyering  <meyering@fb.com>

	maint: enable Automake parallel testsuite harness
	It is better than the older test driver.  It is also the

	minimal version required by Automake 1.11.1.

	avoid silent data loss when an input line is 2^31 bytes or longer
	If one line in a file has length (including newline) of 2^31, then
	applying sed -i to that file truncates it to size 0.  I first
	noticed it like this: Create a file with line of length 2^31-1
	  $ perl -le 'print "v"x(2**31-1)' > k
	Then prepend a byte to that line:
	  $ sed -i 's/^/v/' k
	Surprise!  The file is empty.

	Change the way we treat lines which are not terminated by a newline.
	Such lines are printed without the terminating newline (as before)
	but as soon as more text is sent to the same output stream, the
	missing newline is printed, so that the two lines don't concatenate.

	* sed/execute.c (output_file): Is now struct output; users adjusted
	to access the fp field, call output_missing_newline before, and
	call flush_output afterwards.
	(read_file_line): Set line.chomped FALSE each time we encounter a
	line without the newline terminator, no matter whether this is the
	last input file or not, and no matter whether we are in
	POSIXLY_CORRECT mode or not.

	newline, if necessary.

	(process_files): Don't do the default `p' at the end, ...
	(execute_program): ... as this function is now responsible for it;
	add the code to the end of the function and to the command `q';
	the commands `d', `D' and `Q' thus no longer have to forge an empty
	line.
	(execute_program): Commands `c' and `i' no longer call the
	function output_line with chomped==FALSE; instead, they chomp
	the text and call the function with chomped==TRUE.

Mon Aug 30 23:40:08 PDT 1999  Ken Pizzini <ken@gnu.org>

	*** Version 3.02.80 released

	* sed/execute.c(do_subst): lib/regex.c(re_search_2) seems to
	want one extra backreference register; humor it.

	* sed/regex.c(compile_regex): work around some odd assumptions
	that lib/regex.c(re_compile_pattern) makes about our desired
	RE syntax.

	* configure.in: tweaked version to 3.02.80; added new entries
	to the ALL_LINGUAS definition.

	* doc/sed.1, doc/sed.texi, BUGS: explicitly request the output
	of sed --version in bug-reporting instructions.

	* doc/sed.texi: the old "informal seders list" is dead; document
	the new sed-users mailing list instead (under Other Resources).


Thu Aug 19 23:27:54 PDT 1999  Ken Pizzini <ken@gnu.org>

	* sed/sed.h: Add explicit #include of "regex-sed.h" (rather
	 than relying on parent file doing so); change the "cmd_regex"
	 member of sed_cmd: make it a pointer (instead of a struct),
	 and change its name to cmd_subst; add prototypes for newly
	 exported functions bad_prog(), normalize_text(), compile_regex(),
	 match_regex(), and release_regex(); drop rx_testing variable.

	* sed/compile.c: move the compile_regex() function to regex.c;
	export bad_prog() and normalize_text() functions; eliminate the
	rx_testing debris; rename the NOLEAKS symbol to more descriptive
	DEBUG_LEAKS; make cmd_regex to cmd_subst fixes (see above);
	make use of newly abstracted release_regex() function.

	* sed/execute.c: abstract out the regex matching to
	regex.c:match_regex(); NOLEAKS to DEBUG_LEAKS change;
	cmd_regex to cmd_subst structure member name change.

	* sed/execute.c(do_subst): use re_registers/regoff_t instead of
	regmatch_t to hold the backreference registers, make "offset"
	always be relative to the beginning of the string (rather than
	a delta from "start"), defer some matching bookkeeping (e.g.,
	not_bol_p) to match_regex().

	* sed/sed.c(main): loose rx_testing variable; NOLEAKS
	(aka DEBUG_LEAKS) code attempting to release
	_nl_current_default_domain is problematic, so omit it.

	* sed/regex.c: new file --- abstracts out the interface to the
	regex engine so that less conditional code is required in
	compile.c and execute.c, and so as to make a change of engine
	easier; implements compile_regex() (which looks an awful lot
	like the one that used to live in compile.c), match_regex(),
	and (if DEBUG_LEAKS is set) release_regex().

Sun Apr 18 04:40:46 PDT 1999  Ken Pizzini <ken@gnu.org>

	* sed/sed.c(main): conditionalize calls to setlocale() and
	textdomain() to only occur if their support is needed/wanted.

Sun Apr 18 03:01:46 PDT 1999  Ken Pizzini <ken@gnu.org>

	* bootstrap.sh: "foo || bar && baz" was not grouping like I
	expected ("foo || (bar && baz)") under at least one shell,
	so change the test for a pre-existing config.h file to an
	if statement.

	* bootstrap.sh: added -DUSE_REGEX_GNU_H option to the
	compiler invocation, to ensure that we get a usable
	regex library included.

Sun Apr 18 02:59:42 PDT 1999  Ken Pizzini <ken@gnu.org>

	* sed/sed.h, sed/utils.c: conditionalized inclusion of <libintl.h>
	to occur only if ENABLE_NLS is defined.

Sun Apr 18 01:48:45 PDT 1999  Ken Pizzini <ken@gnu.org>

	* sed/compile.c(xofa,normalize_text,convert_number): change
	name of xofa() function to convert_number(); change semantics
	to do all of the work of the text->number conversion.

	* sed/compile.c(normalize_text): add new \dDDD decimal
	and \oOOO octal escapes.

Sun Mar 28 21:05:07 PST 1999  Ken Pizzini <ken@gnu.org>

	* sed/sed.c(main): if NOLEAKS is set, free up a word that
	the call to textdomain() allocated.

	* sed/execute.c(read_file_line): plug up (minor) memory leak:
	if buffer.alloc==0 we may have malloc()'d 1 byte anyway,
	so be sure to FREE(buffer.text) before calling line_init();

Fri Mar 26 16:52:10 PST 1999  Ken Pizzini <ken@gnu.org>

	* sed/compile.c(match_slash): somewhere between 3.02
	and 3.02a we lost the ability to use a newline as
	the s/// delimiter; restore this ability.

	* sed/compile.c(compile_regex): forget about trying
	to cache the compiled form of the last RE --- it
	causes more problems than its worth.  We now only
	cache the source form.

	* testsuite/help.good: update to reflect output containing
	new options.

Sun Dec  6 00:51:23 PST 1998  Ken Pizzini <ken@gnu.org>

	* sed/utils.c(ck_fwrite): fix i18n bug of using a printf
	fragment of "item%s" to handle plural text.

Mon Nov 23 11:03:40 PST 1998  Ken Pizzini <ken@gnu.org>

	* doc/sed.1, doc/sed.texi: ran ispell over these
	files to catch the more obvious typos...

Sun Nov  1 00:09:07 PST 1998  Ken Pizzini <ken@gnu.org>

	* sed/execute.c(do_list): make a `lcmd_out_line_len'
	(--line-length) of zero mean "infinite length",
	i.e., "never wrap".

Sat Oct 31 23:06:50 PST 1998  Ken Pizzini <ken@gnu.org>

	* execute.c(match_an_address_p,process_files),
	compile.c(compile_program): back out the "zero-address"
	changes of 1998-09-27.  It was a neat idea, but there are
	too many dark corners which don't work well.  The
	special code for handling line ranges starting at
	address zero (from 1998-08-31) are still there though:
	this seems to work fine with no surprises.

Sat Oct 31 22:18:59 PST 1998  Ken Pizzini <ken@gnu.org>

	* sed/sed.c, sed/sed.h, sed/execute.c: added new
	`lcmd_out_line_len' variable.  (Idea suggested by
	Carlos J. G. Duarte <l38076@alfa.ist.utl.pt>.)
	Also added ATOI macro (which uses strtoul() if available,
	with fall-back to atoi()).
	* sed/sed.c(main): attempt to use COLS environment variable
	to set a reasonable `lcmd_out_line_len'; added -l/--line-length
	command-line options to set the new `lcmd_out_line_len' flag.
	* sed/sed.c(usage): documented new -l/--line-length options.
	* sed/execute.c(do_list): use `lcmd_out_line_len' variable
	instead of `LCMD_OUT_LINE_LEN'.
	* sed/execute.c: deleted now obsolete LCMD_OUT_LINE_LEN define.
	* configure.in: added strtoul to the AC_CHECK_FUNCS call.

Sat Oct 31 21:37:17 PST 1998  Ken Pizzini <ken@gnu.org>

	* sed/sed.c, sed/sed.h, sed/execute.c: added new `force_unbuffered'
	flag.  (Idea suggested by Frank Strauss <strauss@escape.de>.)
	* sed/sed.c(main): added -u/--unbuffered command-line options
	to set the new `force_unbuffered' flag.
	* sed/sed.c(usage): documented new -u/--unbuffered options.
	* sed/execute.c: changed the name of the `is_tty' flag in struct
	input to a more generic `no_buffering'; also removed HAVE_ISATTY
	conditional on this member.
	* sed/execute.c(slow_getline): removed HAVE_ISATTY conditonal
	compilation of this function.
	* sed/execute.c(output_line): if force_unbuffered is set,
	then force a fflush() even if writing to stdout.
	* sed/execute.c(open_next_file): added handling of the
	new `force_unbuffered' flag so that slow_getline()
	will always be used for input.
	* sed/execute.c(read_file_line): changed the (conditionally
	compiled) test of `input->is_tty' to (unconditionally)
	use the new spelling `input->no_buffering'.

Thu Oct 15 12:08:09 PDT 1998  Ken Pizzini <ken@gnu.org>

	* configure.in: deleted AC_ARG_PROGRAM call; this is already
	done for us by AM_INIT_AUTOMAKE, and we were winding up
	with a doubled-transform.

Sun Sep 27 01:42:42 PDT 1998  Ken Pizzini <ken@gnu.org>

	* compile.c(compile_program): remove special-case code for matching
	address range with a `0' beginning.

	* compile.c(compile_address): change default addr_number to
	be a pragmatically impossible countT value, instead of zero.

	* execute.c: spell macro REGNEXEC() unconditionally instead of
	playing with conditional definition of regnexec() macro.

	* execute.c(match_an_address_p): added third argument (and changed
	callers in match_address_p).  Added special code to ignore
	non-numeric matches when processing "line zero".

	* execute.c(process_files): added a "line zero" pass through the
	commands script.

Sun Sep 27 00:20:53 PDT 1998  Ken Pizzini <ken@gnu.org>

	* compile.c(xofa,normalize_text): new functions.
	* compile.c(compile_regex): cache last_compiled_re (with its
	associated flags); add POSIXLY_CORRECT behavior for empty RE.
	Make use of the new normalize_text() function.
	* compile.c(setup_replacement): Make use of the new normalize_text()
	function.

Sat Sep 26 22:59:13 PDT 1998  Ken Pizzini <ken@gnu.org>

	* lib/regex-gnu.h: added missing prototype for regncomp().

Mon Sep 14 20:47:23 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/sed.c(main): use EXIT_SUCCESS instead of 0, in case
	we are built on a system (such as VMS) where EXIT_SUCCESS
	is distinct from 0.

Wed Sep  9 22:17:28 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/Makefile.am: added -I../intl the INCLUDES line; if we are
	building in a directory outside the source tree and the system
	we are building on does not have a <libintl.h> header, then
	the build was failing, because libintl.h is a build-time
	constructed source file.

	* configure.in: tweaked version to be 3.02b.

Wed Sep  9 19:28:14 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.02a released

	* sed/compile.c(mark_subst_opts,read_label,compile_program):
	wherever we accept a ; as a command terminator, also allow a } or
	a # to appear.  (This allows for less cluttered-looking scripts,
	such as: sed '/foo/{x;G}' (instead of: sed '/foo/{x;G;}').)

Wed Sep  9 18:17:07 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/compile.c(compile_regex): use regncomp() instead
	of regcomp(), so that a script with NULs in its REs
	will work in the expected manner.

	* sed/compile.c(ADDNUL,REGNCOMP): added support macros
	for above.

	* lib/regex.c(regncomp,regcomp): added regncomp() and
	made regcomp() a simple wrapper function.

Mon Aug 31 21:48:30 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/sed.c(compile_program): if the first address of
	a range is the number 0 (or a 0~N sequence), start
	out in the "a1_matched" state.  This allows one
	to match an initial chunk of a file without undue
	convolutions for handling the case where the match
	for the end of the sequence happens to be the first
	line.

Sun Aug 16 03:34:25 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/compile.c(snarf_char_class,match_slash): simplify
	handling of "premature newline" error. Also, get the
	line number right in the error message if we encounter
	a "premature newline" during char-class snarfing.

Sun Aug 16 02:59:20 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/compile.c: added N_() markers and corresponding gettext()
	(er, _()) calls.

	* Merged in i18n contribution from Erick Branderhorst
	<Erick.Branderhorst@asml.nl>.  His ChangeLog entry
	for the changes I've incorporated so far:

1998-07-24  Erick Branderhorst  <Erick.Branderhorst@asml.nl>
	* configure.in (ALL_LINGUAS, AM_GNU_GETTEXT): nl
	* sed/{sed.h,utils.c}: #include <libintl.h> #define _(String)
	gettext (String)
	* sed/sed.c: #include <locale.h>
	* po/POTFILES.in: sed/{compile,execute,sed,utils}.c
	* run gettextize -f
	* acconfig.h: #undef LOCALEDIR ENABLE_NLS HAVE_CATGETS
	HAVE_GETTEXT HAVE_LC_MESSAGES HAVE_STPCPY

Fri Aug 14 13:52:57 PDT 1998  Ken Pizzini <ken@gnu.org>

	* Merged code from 3.02 with a branched development
	tree from late May; the following (out-of-order)
	changelog entry is from the branched tree.

Sat May 30 12:23:16 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/compile.c, sed/execute.c: added (conditional on NOLEAKS macro)
	code to free all dynamically allocated memory.

	* sed/sed.c, sed/compile.c, sed/execute.c: much shuffling
	of code --- ordered functions such that no forward
	declarations are necessary, and placed all static prototypes
	immediately before the actual function definition.
	This accomplished two things: first, I find the new ordering
	a more natural way to read the code than the previous
	ordering, and second, the new ordering give the compiler
	a better opportunity to discover inlining possibilities.
	(The odd "prototype declaration+old-style definition"
	style is used because I feel it is the least ugly way
	of supporting K&R1 C while still getting the benefit of
	prototypes when they are available.)

	* sed/basicdefs.h: added MEMCPY() macro to hide the VCAST()s
	that ought to be used with memcpy().

	* sed/execute.c: Change calls to memcpy() to go through the
	new MEMCPY() macro.  Various prototypes: elide variable name
	if it does not add any human-useful documentary information
	to the bare type.

	* sed/sed.c(main): Updated calls to compile_string() to add third
	(length) argument.  Changed call to obsolete close_all_files()
	to a call to the new finish_program().

	* sed/sed.c(map_file): Attempt to clean-up how "size" gets
	cast and tested; remove spurious S_ISREG test (just let
	mmap() fail if it doesn't support the underlying file type).

	* sed/sed.c: Deleted old RX library stub declarations.

	* sed/sed.c(map_file,unmap_file): added VCAST()s to the
	mmap()/munmap() calls.

	* sed/utils.c(ck_fclose): added support for ANSI C
	functionality where passing a NULL argument means
	to fclose() _all_ open streams.  (Well, almost.
	Only closes streams which were previously ck_fopen()ed,
	as I don't care to figure out how to autoconf-detect
	whether fclose(NULL) is properly supported on a given
	platform.)

	* sed/sed.h: Renamed `struct text_buf' member `text_len'
	to `text_length'.  Abstracted out `enum addr_types'
	from `struct addr'; added new enum types num2,step,step_mod;
	renamed mod to num_mod.  De-unionized the regex,number,
	{modulo-offset/step} components of `struct addr', in
	anticipation of new features.  Changed type of `a2' member
	of `struct sed_cmd': now a pointer to save space.
	Abstracted out `struct replacement' from `struct subst'.
	Cleaned up declaration of `x' union of `struct addr'.
	Fixed prototype for compile_string().  Replaced prototype
	for old close_all_files() with one for new finish_program().

	* sed/sed.h, sed/compile.c, sed/execute.c: changed to
	simplify the data structures used for branches and
	command blocks: simplified `struct vector'; made
	`struct label' local to compile.c; `struct sed_cmd'
	was modified to support a simpler design for branches
	and blocks.

	* sed/execute.c: Conditionally added ADDNUL() macro so that
	the function call overhead is only incurred if nul_append()
	_must_ be called.  Made some commentary edits, including
	typo fixes.
	* sed/execute.c(resize_line): changed semantics of "len" argument
	from "additional length" to "target length"; made
	INITIAL_BUFFER_SIZE a minimum allocation length.
	* sed/execute.c(str_append): adjusted to new resize_line()
	semantics.
	* sed/execute.c(line_copy): use FREE()+MALLOC() instead of
	REALLOC() to avoid unnecessary copying of old text; add the
	"try doubling first" allocation heuristic (just like
	resize_line() does).
	* sed/execute.c(line_exchange): new function.
	* sed/execute.c(nul_append): make whole function (not just its
	body) conditional on HAVE_REGNEXEC macro; adjust to new
	resize_line() semantics.
	* sed/execute.c(read_mem_line): use str_append() instead if
	custom in-line code; compensate for new default of
	"line.chomped = 0" in read_pattern_space() by setting
	"line.chomped = 1" where appropriate.
	* sed/execute.c(read_file_line): use different trigger to
	determine that "buffer" is uninitialized, and do a full
	initialization if required; use str_append() instead of custom
	in-line code in two places; compensate for new default of
	"line.chomped = 0" in read_pattern_space() by setting
	"line.chomped = 1" where appropriate.
	* sed/execute.c(output_line): don't bother calling ck_fwrite()
	if length==0.
	* sed/execute.c(release_append_queue): new function.
	* sed/execute.c(dump_append_queue): use release_append_queue()
	instead of in-line equivalent.
	* sed/execute.c(read_pattern_space): conditionalize call to
	dump_append_queue() for alleged performance reasons; changed
	default "line.chomped" value to more common "1", and added an
	assignment of "0" where this made a difference.
	* sed/execute.c(match_an_address_p): deleted "is_addr2_p"
	argument; reorder cases to match order in enum declaration; add
	cases for new "addr_is_num2", "addr_is_step", and
	"addr_is_step_mod" address types; alter nul_append() call to be
	through ADDNUL() macro; fix to new struct member and enum
	spellings in (formerly addr_is_mod); addr_is_num_mod case.
	* sed/execute.c(match_address_p): remove oblsolete third argument
	to calls to match_address_p(); alter references to sed_cmd
	member a2 to reflect new pointer status; add new support for
	a2->addr_type addr_is_step and addr_is_step_mod cases.
	* sed/execute.c(do_subst): add NOLEAKS support logic; use
	ADDNUL() wrapper to nul_append(); simplify replacement
	expansion by using the new "struct replacement" data structure;
	use line_exchange() function instead of custom in-line code.
	* sed/execute.c(process_files): added NOLEAKS code.
	* sed/execute.c(execute_program): updated implementations
	of the `{', `}', `:', `b', and `t' commands; modified
	`c' command gratuituosly; fixed potential memory
	overrun in `D' command.  Simplified how nonstandard
	`loop increments' work.  Use line_exchange() instead of
	custom in-line code in 'x' case.
	* sed/execute.c[EXPERIMENTAL_DASH_N_OPTIMIZATION conditional
	code]: various modifications intended to keep this
	code in sync with the new changes, but the code still
	retains its previous bugs.

	* sed/compile.c: use "exit(EXIT_FAILURE) instead of "exit(1)",
	just in case we get compiled under VMS.
	* sed/compile.c: Change type of prog_info.base to decrease needs
	for casting; then elimiated the casts in question ;-).
	* sed/compile.c: Added struct sed_label (moved from sed.h, then
	modified).
	* sed/compile.c: Removed "readit_p" flag from struct fp_list.
	* sed/compile.c: Added module-global "blocks" variable.
	* sed/compile.c: Extracted more error-message constant strings
	to named variables.
	* sed/compile.c(check_final_program): updated to
	reflect new data structures and use new fucntions.
	Added call to compile_regex() to release unneeded
	memory.
	* sed/compile.c: deleted obsolete new_vector() function;
	abstracted new read_label() function; abstracted new
	release_label() function; added new `blocks' module-static
	variable.
	* sed/compile.c(compile_program): updated implementations
	of the `{', `}', `:', `b', and `t' commands; modified
	initialization from NULL vector.
	* sed/compile.c(compile_regex): added mechanism to
	release memory consumed by the cached `last' RE.
	* sed/compile.c(setup_jump,setup_label): updated
	name (from setup_jump to setup_label) and prototype;
	changed body to reflect data structure changes.
	* sed/compile.c: Add OPEN_BRACE and CLOSE_BRACE macros for better
	"vi" editing behavior.
	* sed/compile.c(compile_filename,read_filename,get_writefile):
	Replaced function compile_filename() with more orthogonal functions
	read_filename(), get_writefile().
	* sed/compile.c(compile_regex): Added ability to free the remembered
	"last RE" in compile_regex (for benifit of "NOLEAKS" code).
	* Made adjustments dictated by the change to struct sed_cmd which made
	the a2 member a pointer-to-addr instead of an addr.
	* sed/compile.c(setup_jump,read_label,setup_label,release_label):
	Added functions read_label(), setup_label(), release_label(); deleted
	function setup_jump().
	* sed/compile.c(new_replacement,setup_replacement,release_replacement):
	new functions.
	* sed/compile.c: Adjusted to new spelling of text_buf member
	("text_length" instead of "text_len").
	* sed/compile.c(new_vector): deleted function.  (Due to new handling
	of blocks, only one instance remained, and that one was just as
	clear in-lined.)
	* sed/compile.c(compile_string): Added third argument; it now
	takes a counted string instead of a NUL-terminated string.
	* sed/compile.c(compile_file): added variable "map_base" to
	compensate for new type of prog_info.base.
	* sed/compile.c(check_final_program): reflect new style of
	handling blocks and struct sed_label.
	* sed/compile.c(close_all_files,finish_program): replaced function
	close_all_files() with more generic finish_program().
	* sed/compile.c(read_text): added new feature: if first non-blank
	character after the {a,i,c} command character is not "\", then
	use the trailing text on that line as the (first) line of text.
	Also added code conditional on NO_INPUT_INDENT to support the
	"feature" of stripping leading blanks from each input line; I
	do not read POSIX as permitting this behavior, nor do I think
	it is a good idea, so it is disabled by default, but some have
	argued that this blank-stripping is the "correct" behavior, so
	I offer them the option of building their sed that way.
	* sed/compile.c(compile_address): added xxx,+n and xxx,~n addressing;
	simplified code.
	* sed/compile.c(compile_program): added BAD_PLUS error detection;
	adjusted to new cur_cmd->a2 pointer status; added addr_is_num2
	detection; deleted pointless "a2->addr_number < a1.addr_number"
	check (addr_is_num2 semantics handle this just fine); updated
	code for '{', '}', ':', 'b', and 't' to reflect new design
	of branch handling, including making use of new functions
	related to the new design); added support for feature already
	mentioned in read_text() where {a,i,c} commands are able to have
	their text start on the same line as the command; changed some
	error messages (hopefully for the better); localized variables
	specific to individual commands (particularly 's' and 'y');
	made use of new setup_replacement() function in 's' command.

Mon Aug 10 19:58:49 PDT 1998  Ken Pizzini <ken@gnu.org>

	* doc/sed.texi, doc/sed.1: sedtut10.txt is apparently dead.
	Deleted references to it and added a pointer to
	http://seders.icheme.org/tutorials/.  (Pointed out by
	Joerg Heitkoetter <joerg@de.uu.net>.)

Sat Aug  8 18:11:57 PDT 1998  Ken Pizzini <ken@gnu.org>

	* djgpp/config.btm: per request by Michel de Ruiter
	 <mdruiter@cs.vu.nl>, added "%1" to "%9" parameters.

Mon Aug  3 11:44:55 PDT 1998  Ken Pizzini <ken@gnu.org>

	* doc/sed.texi: fix a couple of typos.  (Submitted by
	Alan Modra <alan@spri.levels.unisa.edu.au>.)

Sat Aug 01 17:49:06 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.02 released

	* configure.in: Because of code change in 3.01a, bump the
	minor revision number for the release (now 3.02).

Sun Jul 26 16:07:55 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01a released

	* sed/compile.c(snarf_char_class):  the POSIX char-class
	recognition loop forgot to update its concept of "prev"
	as the loop progressed.

	* testsuite/Makefile.am: The dependency of version.good
	on [testsuite/]Makefile introduced in the previous
	release was botched -- it referred to "Makefile"
	as "$(srcdir)/Makefile, which of course doesn't work
	if you aren't building in the source tree.

	* djgpp/Makefile.am: add forgotten "config.btm" EXTRA_DIST
	member.

	* configure.in: update version.

Tue Jul 21 06:04:42 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01 released

	* configure.in: mark as release version!

	* Makefile.am: add BUGS and THANKS to the EXTRA_DIST target.

	* testsuite/Makefile.am: add dependency of version.good
	on [testsuite/]Makefile.

Mon Jul 20 12:38:10 PDT 1998  Ken Pizzini <ken@gnu.org>

	* djgpp/config.btm: New file to support the 4DOS alternative
	to command.com.  (Sumitted by Eli Zaretskii on behalf of
	an anonymous 4DOS user.)

Fri Jul 17 00:36:34 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta18 released

	* djgpp/config.sed: my "tweak" in beta17 was too
	hastily considered.  Back it out.

	* configure.in: update to beta18.

Wed Jul 15 01:02:15 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta17 released

        * djgpp/config.sed: tweak/simplify s,,, commands at end.

	* configure.in: update to beta17.

1998-07-14  Eli Zaretskii  <eliz@is.elta.co.il>

	* djgpp/config.sed: Edit all the occurences of = in the context of
	--option=value, including in the help messages, into
	--option:value, but leave DOS-style d:/foo/bar file names intact.

	* djgpp/config.bat: Use --srcdir:foo instead of --srcdir=foo.

	* testsuite/Makefile.am (help, version): Remove temporary files
	explicitly, don't use shell wildcards, so it works under DOS 8+3
	limits.

Thu Jul  9 13:06:00 PDT 1998 16:51:43 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta16 released

	* djgpp/config.sed: tweak the configure script to use :
	instead of = for --with-foo=bar option parsing, to
	work around problems with how command.com handles =s.

Wed Jul  8 16:51:43 PDT 1998  Ken Pizzini <ken@gnu.org>

	* djgpp/config.bat: correct inappropriate behavior that I
	introduced in the beta13 changes (if first argument is
	a directory, it needs to be handled as the --srcdir).

	* testsuite/version.gin, testsuite/version.good, testsuite/Makefile.am:
	Add target to automake to automatically update version.good
	from (new file) version.gin, instead of hand-editing the version
	number each release.

	* testsuite/Makefile.am: miscellaneous gratuitious tweakage --
	mainly adding $(RM) commands just because I didn't like
	leaving the tmp* files from successful runs laying about.
	Also some editorial comments.

	* configure.in: update to beta16.  Added and commented out
	experiment with AC_OUTPUT() for testsuite/version.good.
	Added code to properly handle bare (without =xxx)
	"--with-regex" option.

Sun Jul  5 21:02:16 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta15 released

	* sed/utils.c(ck_fflush), sed/utils.h, sed/execute.c(output_line):
	add and use new ck_fflush() function.

Sun Jul  5 15:23:47 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/compile.c(bad_prog): add more detail to error
	messages about -e strings.

Sun Jul  5 14:29:45 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/compile.c(mark_subst_opts), sed/execute.c(do_subst):
	Define better semantics for interaction of the `g' flag
	with a numeric flag to the s/// command.  It used to
	be that the `g' command siezed control; now the first
	(number-1) matches are skipped and then `g' gets control
	after that.  (It is not clear whether this is a feature
	sneaking in during late beta, or a bug fix; the changes
	involved were trivial, so I decided to treat it as a bug
	fix.)

	* configure.in, testsuite/version.good: update to beta15.

Sat Jul  4 09:54:45 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta14 released

	* sed/basicdefs.h, sed/compile.c, sed/execute.c:
	per report by "Kaveh R. Ghazi" <ghazi@caip.rutgers.edu>,
	copied the ISXXX macros from lib/regex.c so that
	silly machines which require isascii() to be true
	before the other isXXX() macros are valid will
	still work.

	* configure.in, testsuite/version.good: update to beta14.

Thu Jul  2 23:46:13 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta13 released

	* configure.in, acconfig.h: set USE_REGEX_GNU_H symbol if we
	are going to be using lib/regex.c.

	* lib/Makefile.am, lib/regex.h, lib/regex-gnu.h, lib/regex.c:
	rename lib/regex.h to lib/regex-gnu.h, so that those who
	choose to use a different regex implementation will not
	pick-up lib/regex.h when doing "#include <regex.h>".

	* sed/regex-sed.h, sed/Makefile.am, sed/compile.c, sed/execute.c,
	sed/sed.c: create sed/regex-sed.h which acts as a switch
	to choose either lib/regex.h or the user-supplied <regex.h>,
	depending on the value passed to configure's --with-regex=
	option.

Thu Jul  2 17:22:31 PDT 1998  Ken Pizzini <ken@gnu.org>

	* configure.in: if an alternative --with-regex= is given,
	do an AC_CHECK_FUNCS(regnexec regexec) to ensure that
	at least one of these functions is available.  Also,
	parallel changes for the default case.

	* sed/execute.c, acconfig.h: retire use of the WITH_REGNEXEC
	test macro in favor of HAVE_REGNEXEC test macro created
	by above change.

	* djgpp/config.bat: Play games to handle "install-sh",
	DOS filename restrictions, GNU makefile default rules,
	and getting a correct run of "configure" (contributed
	by Eli Zaretskii <eliz@is.elta.co.il>).

	* djgpp/Makefile.am, testsuite/Makefile.am, testsuite/Makefile.in,
	Makefile.am, configure.in: Various automake targets
	(such as distcheck) failed with old configuration.
	The simplest solution was to just add these .am
	files.  (The testsuite/Makefile.in was just renamed to
	testsuite/Makefile.am, then various redundant defines and
	targets were deleted.)  (Reported by Erick Branderhorst
	<Erick.Branderhorst@asml.nl>.)

	* testsuite/dc.good, testsuite/dc.inp: per suggestion from
	Greg Ubben <gsu@romulus.ncsc.mil>, use base 16 output to
	exercise even more of the dc.sed script.

	* configure.in, testsuite/version.good: update to beta13.

Sun Jun 28 16:21:02 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta12 released

	* doc/sed.texi: Avoid mixing @code and @samp markups together:
	they look ugly in Info.  Use @url and @email instead of @example.
	Add indexes.  (Basis of changes contributed by Eli Zaretskii.)

	* djgpp/*, Makefile.am: add support for the DJGPP compiler,
	contributed by Eli Zaretskii <eliz@is.elta.co.il>.

	* dc.sed, testsuite/Makefile.in, testsuite/dc.inp, testsuite/dc.good:
	added this remarkable script, written and contributed
	by Greg Ubben <gsu@romulus.ncsc.mil>, both as a work of
	art for general admiration, and also for use in regression
	testing.

	* configure.in, lib/Makefile.am: add --with-regex=regexlib
	option, which overrides the use of lib/regex.c.

	* configure.in, testsuite/version.good: update to beta12.

Fri Jun 12 16:41:48 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta11 released

	* sed/compile.c: add module-static variables first_script
	(for #n change below) and pending_text (for a/c/i change
	below).

	* sed/compile.c(compile_file), sed/compile.c(compile_program):
	Instead of having #n trigger the -n option in *any file*,
	have #n trigger the -n option only if they are the first
	two bytes of the first script or script-file.

	* sed/compile.c(compile_string), sed/compile.c(compile_file):
	clear the first_script variable at end of these functions.

	* sed/sed.h: tease out the struct text_buf declaration from
	struct sed_cmd, so that a pointer to such can be passed
	to new sed/compile.c(read_text) function.

	* sed/compile.c(compile_program), sed/compile.c(read_text):
	Tease out handling of text to a/c/i commands to new
	read_text() function.  Handle (via aid of pending_text
	variable) texts which span more than one script/script-file
	option.  In particular, restore the ability to have this
	work:  sed -e '1i\' -e 'foo'

	* sed/compile.c(check_final_program): close off any dangling
	pending_text allocation.

Thu Jun 11 11:17:46 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/execute.c(do_subst): fixed two bugs: s/ */X/g was failing
	to match the final empty string after the end of the pattern
	space; and /^foo$/s/o/x/3p was printing, despite the failure
	to do a substition.

Fri Jun  5 04:40:24 PDT 1998  Ken Pizzini <ken@gnu.org>

	* configure.in: change the AC_ARG_WITH(regnexec, ...)
	to be the more appropriate AC_ARG_ENABLE(regnexec, ...).

	* configure.in, testsuite/version.good: update to beta11.

Fri Jun  5 00:54:25 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta10 released

	* sed/execute.c: forgot to P_() the prototype and
	old-style the declaration for bootstrap_memchr()!

Thu Jun  4 18:42:30 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/compile.c(snarf_char_class): added code to
	recognize \n or \<newline> sequence within a
	char-class as the newline character.

Tue Jun  2 11:56:02 PDT 1998  Ken Pizzini <ken@gnu.org>

	* configure.in: added check for <sys/types.h> and
	a AC_ARG_WITH(regnexec,...) check, to simplify use
	of other regex libraries which have regexec() but
	not regnexec(), with the corresponding loss of
	functionality (regexps will not work right against
	input lines which contain NULs).

	* sed/execute.c: add nul_append() function, a #define
	for a regnexec() -> regexec() macro (conditional on
	the lack of the WITH_REGNEXEC symbol), and a couple
	of calls to nul_append() (in match_an_address_p()
	and do_subst()) to permit the use of the POSIX standard
	regexec() function call instead of the suggested
	regnexec() call.

	* sed/compile.c, sed/execute.c, sed/sed.c: check for
	<sys/types.h> and include it (before "regex.h") if
	available.  This makes it simpler to use the system's
	regex library instead of the one in lib/regex.c, should
	that be desired.

Tue Jun  2 08:41:05 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/basicdefs.h: define VCAST macros to allow sed to
	compile on systems which predate the definition
	of "void *", and yet still get feedback about
	stupid programming errors from systems which *do*
	know about "void *"s.  Also define MALLOC, REALLOC,
	MEMDUP, and FREE macros to keep under control the
	degree of code ugliness which would otherwise be
	introduced in making use of the VCAST macro.

	* sed/compile.c, sed/execute.c, sed/sed.c, sed/utils.c:
	pervasively use the new VCAST, MALLOC, REALLOC, MEMDUP,
	and FREE macros wherever appropriate.

	* sed/utils.c, sed/utils.h: correct type of first arguments
	to ck_fread() and ck_fwrite() to be [const] VOID *.

	* sed/basicdefs.h, sed/execute.c: protect against
	the rumored systems which stupidly #define __STDC__ 0.

	* testsuite/help.good, testsuite/Makefile.in: make
	the ``help'' test insensitive to the spelling of
	the executable's name.  Also, enhanced `make clean'
	target.

	* doc/sed.texi, doc/sed.1: correct documentation of `q'
	command; fix typos.

	* configure, testsuite/version.good: update to beta10.

Sat May 30 17:28:00 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta9 released

	* Makefile.am: make testsuite a normal SUBDIR.

	* configure.in: discontinue using AC_ISC_POSIX --
	check for -lcposix library instead; added
	testsuite/Makefile to AC_OUTPUT list.

	* lib/memmove.c(memmove): fixed wrong sense used
	for HAVE_BCOPY test.

	* sed/execute.c: checked more specifically for a version
	of gcc which supports __attribute__ (i.e., >= 2.7).

	* testsuite/*: renamed files to fit 14 char limit.

	* testsuite/Makefile, testsuite/Makefile.in: Makefile
	renamed to Makefile.in and then modified so that
	"make -j check" from top directory will work.

	* testsuite/subwrite.sed, testsuite/writeout.sed: changed
	file name of the "w" command to be consistent with the
	new naming used in testsuite/Makefile.in.

	* doc/sed.1, doc/sed.texi: fixed some typos, formatting
	glitches, and poor wordings.

Sat May 30 04:02:29 PDT 1998  Ken Pizzini <ken@gnu.org>

	* configure.in: specify that config.h is to be derived
	from config_h.in in order to avoid the braindead
	DOS file system limitations.

Fri May 29 21:56:30 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/compile.c(compile_address), doc/sed.texi: gave
	a better definition to the meaning of N~0 address
	forms -- N~M addresses now mean that lines match
	when there exists a non-negative x such that
	lineno == N+x*M.

Fri May 29 12:07:38 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/compile.c(compile_address),
	sed/execute.c(match_an_address_p): update semantics of
	N~M address form: now N is the first line which will
	match and M is the step between succeeding matches.
	If N<M this works out to the same as before, but the
	new behavior for N>=M seems more useful.

	* doc/sed.1, doc/sed.texi: update documentation of N~M
	address form; added "Other Resources" node to sed.texi;
	minor formatting changes to some items in sed.1 with
	an eye to improving clarity.

	* configure.in, testsuite/version.good: update to beta9.

Sat May 23 20:04:31 HST 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta8 released

	* sed/compile.c(compile_regex): forgot to make last_re be
	a *copy* of the buffered text in today's earlier fix.

	* sed/execute.c(read_file_line): EOF check was wrong --
	it forgot to allow for the possibility that we were
	appending to the end of the ``line'' (instead of merely
	reading a fresh line).

Sat May 23 18:07:18 HST 1998  Ken Pizzini <ken@gnu.org>

	* sed/compile.c(compile_regex): don't track compiled version
	of regex -- the modifiers may change.  Track the regex
	source instead.  (For "last regex" (aka //) notation.)

	* configure.in, testsuite/version.good: update to beta8.

Sat May 23 16:07:09 HST 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta7 released

	* sed/execute.c: #undef'd EXPERIMENTAL_DASH_N_OPTIMIZATION
	because its code is buggy.

Tue May 19 17:03:52 HST 1998  Ken Pizzini <ken@gnu.org>

	* sed/sed.c: label rx library code as such with #ifdefs
	(instead of just #if 0).

	* sed/compile.c(compile_program): make incremental
	improvement to the "Unknown command" error message.

Sat May 16 23:16:26 HST 1998  Ken Pizzini <ken@gnu.org>

	* testsuite/Makefile: simplify: get rid of automatic run
	against system's sed; don't time by default; allow for
	alternative comparison command.

	* configure.in, testsuite/version.good: update to beta7.

Wed May 13 21:44:28 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta6 released

	* lib/Makefile.am: fix spelling of libsed_a_LIBADD in
	libsed_a_DEPENDENCIES.

	* configure.in, testsuite/version.good: update to beta6.

Wed May 13 14:38:08 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta5 released

	* sed/execute.c(do_subst): added not_bol_p variable to track when
	we have iterated past the beginning of the pattern.
	[Thanks to Jim Meyering <meyering@ascend.com> for the bug report.]

Wed May 13 13:54:04 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/execute.c(bootstrap_memchr): new function.  When
	bootstrapping we don't know if we are on a 64-bit machine,
	so lib/memchr.c breaks.  Supply this (slow) implementation
	just to get us bootstrapped.

	* bootstrap.sh: add a #define BOOTSTRAP symbol; add -I.
	for emphasis for the compiles in sed/; be explicit
	about what files we're bothering to compile.

	* configure.in, testsuite/version.good: update version
	to beta5.

Wed May 13 06:39:06 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta4 released

	* rename writeout.good? to wrtout?.good and subwrite.good? to
	subwrt?.good to comply with DOS 8+3 file name restrictions.
	[Eli Zaretskii <eliz@is.elta.co.il> suggested this to
	simplify DJGPP ports, and it was easy.]

	* testsuite/Makefile: reflect above name changes.

Wed May 12 21:09:32 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/sed.c(usage): fix non-portable omission of \n\ at end of
	lines within long string.

	* sed/sed.c(main): remove spurious argument to fprintf() in the
	'V'ersion output.

	* sed/execute.c(line_append): embed newline between the two
	text fragments unconditionally.

	* sed/execute.c(do_subst): change structure assignment to memcpy()
	(for portability reasons).

	* README.bootstrap: suggest using -w option.

Tue May 12 10:02:37 PDT 1998  Ken Pizzini <ken@gnu.org>

	* configure.in: use AC_REPLACE_FUNCS where appropriate.

	* lib/Makefile.am: updated to reflect AC_REPLACE_FUNCS change in
	configure.in.

	* lib/memchr.c lib/memcmp.c: revert to standard GNU versions.

	* lib/alloca.c: added this missing file.

	* testsuite/version.good: updated for new version identifier.

Mon May 11 18:50:56 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta3 released

	* sed/Makefile.am: fix INCLUDES to work right with VPATH.
	[Thanks to Jim Meyering <meyering@ascend.com> for the bug report.]

	* sed/sed.c(usage): make --help output more user-friendly?

	* sed/execute.c(execute_program): fix bug in 'x' command introduced
	in the alleged portability fix of May 9.

	* configure.in: update version to 3.01-beta3.

	* testsuite/version.good, testsuite/help.good: freshen with
	latest output.

Sat May  9 22:35:45 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta2 released

	* sed/sed.c: add #include <sys/types.h> in HAVE_MMAP
	block (needed on some machines).

	* lib/memmove.c: #include <memory.h>, if HAVE_MEMORY_H.

Sat May  9 21:29:00 PDT 1998  Ken Pizzini <ken@gnu.org>

	* configure.in: remove dangling references to rx library;
	added HEADER and FUNC checks for items used by source in
	lib/.

	* lib/ansidecl.h, lib/memcopy.h, lib/pagecopy.h, lib/string.h
	lib/memcpy.c, lib/memmove.c: deletes these files.  There
	are still pieces of glibc missing to support these, and
	it isn't worth the headache right now.

	* lib/memmove.c: de novo, simpler version.  Uses bcopy()
	if available, and slow-but-simple code if not.

	* lib/Makefile.am: remove references to deleted files.
	Added forgotten reference to memcpy.c.  Re-ordered
	SOURCE entries to reflect dependencies for systems
	which lack ranlib.

	* sed/basicdefs.h: updated to reflect above changes to lib/,
	and experience with non-STDC compilers.

	* lib/regex.c: made regerror() function publicly visible.

	* lib/strerror.c: use old-style function declaration.

	* sed/compile.c, sed/execute.c, sed/sed.c, sed/utils.c,
	sed/sed.h, sed/utils.h: ensure that private definitions of
	some symbols do not cause problems when #include'ing system
	headers (mainly by re-ordering the #include directives).
	(This is particularly an issue for bootstrap.sh runs.)

	* sed/execute.c (execute_program): use memcpy() instead of
	structure assingment ('x' command), for portablility to
	old compilers.

	* sed/execute.c (slow_getline): use old-style function
	declaration, with a P_ prototype.

	* sed/sed.c: change the type of the fallback MAP_FAILED
	definition to work on archaic systems.  (Modern systems
	should be defining it themselves, so the change from
	void * shouldn't be a problem.)

	* bootstrap.sh, README.bootstrap: actual testing of bootstrap
	code revealed that I was too optimistic.  Redesigned and
	replaced implementation.

	* testsuite/Makefile: ignore errors from reference-implementation
	seds that aren't up to snuff.

	* testsuite/help.good, testsuite/version.good: update to
	current version's output.

Fri May  8 15:08:28 PDT 1998  Ken Pizzini <ken@gnu.org>

	*** Version 3.01-beta1 released

	* sed/sed.c (main, usage): once again tweak the --help and
	--version output to bettery comply with GNU coding standards.

	* testsuite/help.good, testsuite/version.good: update to
	reflect above change.

	* doc/sed.texi: fix "Invoking" node's spelling to comply
	with GNU standards.

Fri May  8 11:43:10 PDT 1998  Ken Pizzini <ken@gnu.org>

	* doc/sed.1, doc/Makefile.am: wrote (very basic) man page.

Thu May  7 20:40:21 PDT 1998  Ken Pizzini <ken@gnu.org>

	* lib/Makefile.am, lib/memmove.c, lib/memchr.c, lib/regex.c,
	lib/memcpy.c, lib/regex.h, lib/memcopy.h, lib/string.h,
	lib/pagecopy.h, lib/ansidecl.h: grab yet-another-version
	from gnu.org for baseline and/or edit copyright boilerplate
	using official lgpl2gpl.sed script.  Take care not to
	loose regnexec() interface or special conditional-compilation
	code.

Wed May  6 23:35:12 PDT 1998  Ken Pizzini <ken@gnu.org>

	* lib/regex.c, lib/regex.h: take from grep-2.1 distribution,
	then trivially added the regnexec() interface.

	* sed/sed.c, sed/compile.c, sed/execute.c: made modifications
	to work with regex instead of rx.

	* rx/*: deleted directory; the code is just too slow.
	I think it will be easier to extend regex to fully
	support POSIX.2 than to tune rx to be reasonable.
	Even if this supposition is wrong, I'd rather make
	the 3.01 release with the slightly deficient regex.

	* Makefile.am lib/Makefile.am, sed/Makefile.am: made changes
	related to the substitution of regex for rx.

	* lib/Makefile.am, sed/Makefile.am: since regex is not a
	``compatability'' module, changed name of library to
	``libsed.a''.

	* lib/memchr.c, lib/memcpy.c, lib/memmove.c: add conditional
	compilation code to leave zero-sized .o file if system
	already supports the implemented function.

	* testsuite/help.good, testsuite/version.good: brought
	up-to-date (once again).

	* NEWS, ANNOUNCE: changes to reflect this batch of changes.

Wed May  6 18:40:47 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/execute.c: discovered awful bug in '}' handling:
	it could read past the end of vec (because `n' was
	being decremented below zero)!  Needed to "continue"
	instead of "break".

Tue May  5 14:34:38 PDT 1998  Ken Pizzini <ken@gnu.org>

	* doc/sed.texi, doc/version.texi: wrote some rudimentary
	texinfo documentation.

	* ANNOUNCE, NEWS, README, README.rx, Makefile.am:
	more updates for the upcoming beta-release.

	* sed/compile.c, sed/execute.c, sed/sed.c, sed/utils.c,
	sed/sed.h, lib/strerror.c: update copyright notice text.

Fri May  1 15:41:37 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed/execute.c (match_an_address_p, match_address_p): if
	the second element of an address range is a line number,
	and that line number is *less than* (or equal to) the
	current line number, we only match the one line (per
	POSIX.2, section 4.55.7.1).  [Bug discovered as reported
	in the seders mailing list FAQ.]

	* AUTHORS, NEWS, acconfig.h, configure.in, doc/Makefile.am,
	lib/Makefile.am, sed/Makefile.am, lib/README,
	testsuite/help.good, testsuite/version.good:
	Updated in anticipation of the 3.01-beta1 release.
	Reorganized development source tree to make creation
	of a distribution simpler.  Most notable changes were
	to the various Makefile.am files and configure.in, but
	some minor edits (such as deleting or changing #include
	directives) have been made in many other source files.

	* bootstrap.sh, README.bootstrap: created a mechanism for
	creating sed on a system which lacks a working sed.

Thu Apr 16 23:52:11 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed.h, sed.c, execute.c, compile.c: did a spell-check on
	the comments; fixed several typos.

Thu Apr 16 13:43:01 PDT 1998  Ken Pizzini <ken@gnu.org>

	* execute.c (do_subst): fixed bug where the "replaced" flag
	was being set to one inappropriately when at least one
	but fewer than sub->numb matches of the regexp were found.
	(Thanks to Simon Taylor <staylor@hermes.iaccess.com.au>
	for the bug report.)

Wed Apr 15 11:35:31 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed.h, sed.c, compile.c, execute.c: having a concern that
	a cast was being done inappropriately, and realizing that
	there is no quick way to locate all casts in a program, I
	went through and marked all casts with a simple macro.
	Now it is a simple matter to locate the casts, and it is
	also a simple matter to turn of casts for a lint session
	(if it should be desired).

Wed Apr 15 10:29:21 PDT 1998  Ken Pizzini <ken@gnu.org>

	* compile.c, sed.c: redo compile phase so that brace
	expressions can be spread across multiple files.
	For example:
	  printf '{' >a; printf 'l;d' >b; printf '}' >c
	  sed -f a -f b -f c foo
	will now compile (and work), instead of complaining
	about an unmatched '{'.  The mess created in compile.c
	allowed a little simplification to the command-line
	processing of "-e" options in sed.c.

	sed.h: added (opaque) err_info member to struct vector;
	added comments to the members of struct vector.

Wed Apr 14 23:50:50 PDT 1998  Ken Pizzini <ken@gnu.org>

	* sed.h, sed.c, compile.c, execute.c: added types countT and
	flagT in order to clarify what various "int"s were doing.
	Also makes it easy to change the type used for counts
	(for example, to "unsigned long long") if desired, although
	there are still some gotchas (such as the printf() format
	for the '=' command).

Tue Apr 14 17:34:54 PDT 1998  Ken Pizzini <ken@gnu.org>

	* execute.c (execute_program, process_files, count_branches,
	shrink_program): Added a first attempt at program optimization.
	We now can quit early if we are running with the "-n"
	and all of the commands are known to be valid only for
	lines less than the current line.  Thus the "sed" in
	"foo | sed -n 1,2p" will print read three lines, printint
	the first two, and then quit, regardless of how much longer
	"foo" might run or output.  This optimization does not buy
	much in most cases (it sometimes even costs a little),
	but when it does help it can help big.  The code is
	all conditionally compiled based on the
	EXPERIMENTAL_DASH_N_OPTIMIZATION symbol being #defined,
	so it can be easily omitted if it causes problems.

Tue Apr 14 12:25:06 PDT 1998  Ken Pizzini <ken@gnu.org>

	* execute.c (test_dollar_EOF, last_file_with_data_p):
	test_dollar_EOF() was incorrectly returning a false (0)
	when there were unprocessed files, none of which had any
	data (either unopenable or zero-length).  Created
	last_file_with_data_p() to detect this situation, and
	modified test_dollar_EOF() to make use of it.

Thu Apr  2 23:02:18 PST 1998  Ken Pizzini <ken@gnu.org>

	* compile.c (match_slash): match_slash() did not handle
	[.coll.], [=equiv=], and [:class:] sequences within a
	character class.  Added snarf_char_class() [which is a
	remote derivative of parse_char_class() from GNU ed-0.2]
	to deal with the details, and altered match_slash()
	to make use of it.  Also created the trivial
	add_then_next() to avoid clutter in snarf_char_class().

Thu Apr  2 20:34:42 PST 1998  Ken Pizzini <ken@gnu.org>

	* execute.c, sed.c, sed.h: There was a severe bug in
	how the code handled "sed 5n a b" when "a" consists
	of exactly five lines -- it behaved like "sed 5q a b"!

	Rearranged where files get opened -- large scale
	changes primarily involving main(), process_files(),
	and read_pattern_space(), but also touching on several
	other parts of execute.c.  The read_pattern_space()
	function became unwieldly and parts were split into
	open_next_file(), closedown(), read_always_fail(),
	read_mem_line(), and read_file_line().  The
	at_end_of_file_p() function became obsolete and was
	eliminated; test_dollar_EOF_p() was updated.  A few
	global and module-static variables were elminated, and
	"struct line" was extended; comments were added to the
	"struct line" declartation to document some important
	dependencies in it.

	I undertook the reorganization with dread, but I
	feel that the new organization is an improvement
	well beyond just fixing the bug that inspired it.

Thu Apr  2 01:16:25 PST 1998  Ken Pizzini <ken@gnu.org>

	* execute.c (read_file_line, slow_getline): the fread()
	buffering code gives insufficient feedback to a user
	running sed with a tty input device, so I created
	slow_getline() for reading from a tty device.
	Additionally, EOF detection has been made a little more
	sensitive to avoid requiring multiple EOFs to be entered
	from a tty.

	* configure.in: added isatty() check.

Wed Apr  1 11:04:30 PST 1998  Ken Pizzini <ken@gnu.org>

	* configure.in (CPPFLAGS, LDFLAGS, LIBS):
	Set to appropriate values if large file support needs
	explicit enabling.  Code fragment taken from a 1997-10-25
	patch to gawk by Paul Eggert <eggert@twinsun.com>

Thu Aug 14 17:43:27 PDT 1997  Ken Pizzini <ken@gnu.org>

	* utils.c (ck_fclose): modified to ignore NULL parameter.

Thu Aug 14 12:08:45 PDT 1997  Ken Pizzini <ken@gnu.org>

	* execute.c: tweaked execute_program() to eliminate
	gratuitous "goto" usage.

Thu Aug 14 11:30:04 PDT 1997  Ken Pizzini <ken@gnu.org>

	* compile.c: added case-insensitive modifier ('I') to
	address and s/// regexps.  The s/// case also accepts
	the more popular 'i' modifier.  (The address regexp
	cannot use 'i' as a modifier, as that conflicts with
	the use of the 'i'nsert command.)

Thu Aug 14 09:29:06 PDT 1997  Ken Pizzini <ken@gnu.org>

	* compile.c: abstracted out match_slash() from the s///, y///,
	and address-regexp special-case codes.

	* execute.c: made dump_append_queue() use ck_fread() instead
	of hand-rolled error checking.

Mon Jul 28 10:50:41 PDT 1997  Ken Pizzini <ken@gnu.org>

	* sed.c, sed.h, execute.c: POSIX.2, section 4.55.7, says that
	a newline must end *every* output line.  But I think that
	it is useful (when seding a binary file) to omit a trailing
	newline if the input lacks one.  Thus the addition of
	POSIXLY_CORRECT behavior.

	* execute.c: however, when seding multiple files my feeling
	is that it makes sense to have each file but the last
	behave as-if it ended in a newline.  Modified read_pattern_space()
	accordingly.

	* utils.c: realized that add1_buffer(), for performance reasons,
	shouldn't be calling memcpy() (indirectly via add_buffer()),
	so rewrote it.

Sat Jul 26 23:08:28 PDT 1997  Ken Pizzini <ken@gnu.org>

	* execute.c: attempted to make read_pattern_space more
	efficient for the the non-mmap() case.

	* utils.c, utils.h, execute.c: new function ck_fread()
	created and used.

Sat Jul 26 20:22:14 PDT 1997  Ken Pizzini <ken@gnu.org>

	* execute.c, compile.c, sed.c: abstracted the mmap()
	interface into map_file()/unmap_file() [sed.c], and
	changed the ad-hoc code in compile_file() [compile.c]
	and process_file() [execute.c] to make use of the new
	interface.

Sat Jul 26 19:45:46 PDT 1997  Ken Pizzini <ken@gnu.org>

	* execute.c, compile.c, configure.in: Check to see if mmap()
	is available; if so make use of it on regular files.

	* compile.c: compile_file() now closes the input file
	when it is through!

Sun Jul 20 23:57:02 PDT 1997  Ken Pizzini <ken@gnu.org>

	* compile.c: modified parsing to permit whitespace in more
	places where it makes sense;
	added backslash escaping to the y/// command, per POSIX.

	* execute.c: Merged append_pattern_space() into read_pattern_space();
	moved body of 's' command to new function do_subst();
	moved body of 'l' command to new function do_list();
	changed output of 'l' command to conform to POSIX.2;
	made line handling conform to POSIX; added output_line() function;
	redesigned append-space algorithm; added append_queue structure and
	the next_append_slot() and dump_append_queue() functions.

	* sed.h: moved the definition of what is now struct subst
	outside of the definition of struct sed_cmd.

Sat Jul 19 16:29:09 PDT 1997  Ken Pizzini <ken@gnu.org>

	* sed.c, execute.c, sed.h, Makefile.am: Separated out the
	pieces dealing with executing the program from the top-level
	parameter parsing and control.

Sat Jul 19 01:16:35 PDT 1997  Ken Pizzini <ken@gnu.org>

	* sed.c, compile.c, sed.h, Makefile.am: separate out the
	pieces dealing with compiling the program from the pieces
	dealing with interpreting the result.

	* compile.c: add functions in_nonblank() and in_integer(),
	and change interface to compile_address() with an eye
	to making code clearer.

Fri Jul 18 13:35:50 PDT 1997  Ken Pizzini <ken@gnu.org>

	* utils.c: attempt at a quasi-unification of the
	STDC and traditional C approaches to panic().

	* sed.c: eliminate some gratuitous bit twiddling.
	(Using flag bits can be a useful technique, but
	this code is cleaner without them.)

	* sed.c: place mutually exclusive members of struct addr
	within a union, mainly to document the exclusivity;
	eliminate unused structure members from struct fp_list;
	eliminate unnecessary module-global variables;
	remove some #if 0 code that is too odd to keep;
	allegedly simplified the 'l' case of execute_program();
	allegedly simplified inchar();
	localized some static variables;
	renamed some variables to better document their purpose;
	removed some goto-s rendered obsolete by other changes.

Thu Jul 17 15:30:44 PDT 1997  Ken Pizzini <ken@gnu.org>

	* utils.c, utils.h, sed.c: added and made use of
	ck_free() function.

	* utils.c, utils.h, sed.c: changed all the *_buffer()
	functions to take/return an incomplete type
	"struct buffer *" instead of using VOID *.

	* utils.c, utils.h, sed.c: renamed "finish_buffer()"
	to "free_buffer()", on the premise that the new
	name better describes the function's purpose.

Wed Jul 16 13:52:14 PDT 1997  Ken Pizzini <ken@gnu.org>

	* utils.c, utils.h, sed.c: added and made use of
	ck_memdup() function.

	* sed.c: protected a call to add1_buffer() in
	compile_program() which could have tried to
	push an EOF if a a/i/c command ended with
	a '\', EOF sequence.

	* utils.c: added sanity check to add1_buffer() so that
	EOF will not be added to the buffer.

Wed Jul 16 03:56:26 PDT 1997  Ken Pizzini <ken@gnu.org>

	* configure.in, compat.h, compat.c: added memchr.

	* sed.c: got rid of arbitrary NUM_FPS limit;
	made global functions and variables "static" where appropriate;
	make various cosmetic changes, hopefully improving readability;
	simplified some redundant predicates;
	simplified some code, but nothing fundamental (yet?).

Wed Jul 16 00:24:54 PDT 1997  Ken Pizzini <ken@gnu.org>

	* alloca.c, getopt.c, getopt.h, getopt1.c: updated from
	versions in textutils-1.22.

	* Makefile.in, Makefile.am, configure.in: put in automake support.

	* basicdefs.h, compat.h, compat.c [, sed.c, utils.c]: took out
	some very ugly compatibility #ifdefs and packaged into one
	place.

	* sed.c, utils.c: some gratuitous formatting changes.

	* utils.c: changed datatype of utils_id_s in order to
	eliminate arbitrary array size.

Sun Jul 13 17:00:26 PDT 1997  Ken Pizzini <ken@gnu.org>

	* sed.c, utils.c, utils.h: de-linting oriented cleanup.

Sun Jul 13 00:46:48 PDT 1997  Ken Pizzini <ken@gnu.org>

	* sed.c: fixed bug which caused SEGV for files missing a
	final newline.  Corrected calls to regnexec to pass the
	proper parameters, in the proper order.

Sat Dec 30 20:16:59 1995  Tom Lord  <lord@beehive>

	*** Version 3.00 released

	* sed.c: Use posix entry points to regexp functions.
	Fix enough bugs to pass the test-suite.

....... Jason Molenda  <crash@cygnus.com>

	* testsuite/: trippy test suite.


Wed May 11 07:46:24 1994  Chip Salzenberg  (chip@fin.uucp)

	*** Version 2.05 released

	* sed.c (compile_address): Recognize numeric addresses.
	Fixes typo made during installation of "~" feature.

Sat Apr 30 17:17:38 1994  Tom Lord  (lord@x1.cygnus.com)

	*** Version 2.04 released

	* sed.c: applied a patch from
	 From: kap1@tao.cpe.uchicago.edu (Dietrich Kappe)

	 Dietrich writes:

	 As my contribution to the creeping feature creature in sed,
	 here is a new type of address. The address has form n~m,
	 which means "the line number is equal to n modulo m." The
	 modifications to sed are trivial, and the general
	 usefulness of this address should be obvious. If m is 0 or
	 missing, 1 is used in its place (could be a bug or a
	 feature :-).

Sat Apr 30 17:17:38 1994  Tom Lord  (lord@x1.cygnus.com)

	* rx.c (solve_destination): protect `solution' more carefully.
	This is a cleanup of a patch from Kevin Buettner
	 (kev@cujo.geg.mot.com).

Sat Apr 30 17:17:38 1994  Tom Lord  (lord@x1.cygnus.com)

	* rx.c: make translation tables unsigned chars

	* sed.c (main): Compile accumulated -e commands as
	soon as a -f command comes along.  This ensures that
	the commands are executed in the right order.

Mon Oct 25 14:41:47 1993  Tom Lord  (lord@rtl.cygnus.com)

	* sed.c (execute_program): 'w' flushes the buffer after it
	writes -- diagnosed by doug@research.att.com.  'r' and 'w' to
	the same file is now supported -- hopefully even in a way that
	satisfies Posix (it now behaves differently from some
	/bin/sed's and the spec is hard to read so i'm not sure).

	Also, 'r' of a non-existent file is now permitted.

Mon Oct 11 21:06:10 1993  Tom Lord  (lord@cygnus.com)

	* sed.c (execute_program): remember that 'b' and 't' are more
	like longjmp than goto.  Patch from tom@basil.icce.rug.nl (Tom
	R.Hageman)

	* rx.c: patch from From: fin!chip@rutgers.edu (Chip
	Salzenberg) to get rid of compiler warnings.


Sat Aug  7 01:04:59 1993  Tom Lord  (lord@unix7.andrew.cmu.edu)

	*** Version 2.03 released

	* sed.c (compile_regex): report error messages for bogus
	regexps.

	SEE ALSO:  ChangeLog.rx


Wed Jul 21 00:28:03 1993  Tom Lord  (lord@unix8.andrew.cmu.edu)

	* alloca.c: upgraded to a more recent version

	* rx.c (re_search_2): prefer matches with longer
	subexpressions to those with shorter ones, giving precedence
	to low numbered subexpressions.

	* rx.c (re_compile): don't free `params' if its null.

Fri Jul 16 01:12:08 1993  Tom Lord  (lord@unix8.andrew.cmu.edu)

	* rx.[ch], sed.c: rx replaces regex.



Thu May 27 11:13:03 1993  Tom Lord  (lord@unix3.andrew.cmu.edu)

	* sed.c (execute_program, match_addr): caught more cases
	that need to be sensitive to a missing \n at EOF.

Fri May 21 00:39:22 1993  Tom Lord  (lord@unix8.andrew.cmu.edu)

	* sed.c (execute_program): apply gaumondp's patch
	to fix '\xabcxs/foo/bar/'.

	* sed.c (execute_program):
	If a second address is a regexp, never match it on the
	same line as the first address.

	* sed.c (compile_regexp):
	Numeric ranges  x,y s.t. y < x are now treated as x,x.
	There was a bug in that they were being handled like x,x+1.

	* sed.c (execute_program, read_pattern_space,
	append_pattern_space) don't add newlines to lines
	that don't have them.

Wed May 19 13:34:45 1993  Tom Lord  (lord@unix9.andrew.cmu.edu)

	* sed.c (compile_program): grok \\n in comments.

Mon May 17 16:34:50 1993  Tom Lord  (lord@unix9.andrew.cmu.edu)

	* alloca.c: new (standard) file

	* configure.in: AC_CONSTified

	* sed.c (compile_program): properly diagnose the error of
	a missing command (e.g. sed /x/). (thanks gaumondp)

	* sed.c (compile_regexp): handle character classes correctly.
	Thanks gaumondp@ERE.UMontreal.CA
	and  schwab@issan.informatik.uni-dortmund.de.

Thu May  6 12:37:18 1993  Tom Lord  (lord@unix10.andrew.cmu.edu)

	* sed.c (compile_filename, execute_program): don't use
	`access' or `/dev/null'.

	* sed.c (execute_program): 'N' at EOF should delete the pat buf.

	* sed.c (compile_filename): truncate, don't append files
	being openned for `w' or `s///w'

	* sed.c (execute_program): -n switch shouldn't effect `i' or `c'.

	* sed.c (compile_program): don't compile unescaped newlines
	into the substitution string of an `s' command (they are an error).

	* sed.c (compile_regex): correctly skip over character
	sets that contain `]'.

	* sed.c (execute_program): patch from gaumondp
	Correctly handle empty-string matches in the case of an `s'
	command with a repeat count.

	* sed.c (compile_program): patch from gaumondp@ere.UMontreal.ca.
	Don't consume characters after the label of a `b', `t' or `:' command.

	* sed.c (compile_program): unmatched open braces are an error.

	* sed.c (compile_file): when consuming an initial comment,
	count lines correctly.

Wed Nov 18 02:10:58 1992  Tom Lord  (lord@unix2.andrew.cmu.edu)

	* sed.c (execute_program): Made s///p print even if -n was
	specified.

	* sed.c (compile_string): Changed the type of this function to
	fix a compile warning.

Wed Nov  4 17:15:34 1992  Tom Lord  (lord@unix7.andrew.cmu.edu)

	* sed.c (main): Initialize the hold area to contain "\n"
	instead of "".  In execute_program, all lines are expected
	to be newline terminated.  Also, if H is the first command
	in the script, the result is a pattern buffer that begins
	with a blank line.  Thanks to pinard@iro.umontreal.ca
	(Francois Pinard) for pointing out this and many other bugs.

	* sed.c (execute_program): Fixed a case of `D' command.
	Thanks Chris Weber <weber@bucknell.edu>

	* sed.c: added new tests of no_default_output to make -n work.
	Thanks Andrew Herbert <andrew@werple.apana.org.au>

	* sed.c, configure.in,Makefile.in: autoconfed bcopy and const.
	Thanks "J.T. Conklin" <jtc@gain.com>

	* sed.c: made prog_cur, prog_start, and prog_end unsigned so
	that users could write  `sed -e s/�/foo/g'.

Tue Oct 13 00:04:05 1992  Tom Lord  (lord@unix3.andrew.cmu.edu)

	* sed.c (execute_program): fixed the cycling behavior of 'D'

	* sed.c: integrated patch that closes files

	* sed.c: changed regexp syntax

Fri May 22 15:11:12 1992  Tom Lord  (lord at moriarty.bh.andrew.cmu.edu)

	* regex.c:  this is not my change, but a pointer to the fact
	that karl@gnu fixed some regexp bugs that were plaguing sed.

Thu Apr 30 13:02:21 1992  Tom Lord  (lord at unix3.andrew.cmu.edu)

	* sed.c (compile_program, execute_program)
	subprograms are now compiled with an explicit continuation ;)
	return_v and return_i in struct vector.  execute_program
	no longer recurses to execute subprograms (case '{') and now
	understands a return instruction (case '{').

Tue Apr 28 17:13:04 1992  Tom Lord  (lord at unix7.andrew.cmu.edu)

	* sed.c (compile_address) added \?regexp? syntax for addresses.

	* sed.c (main) added {} intervals to the obscure regexp
	syntax.

	* sed.c (compile_program)  after calling compile_address,
	normalize numeric addresses (make a2.addr_number > a1.addr_number).
	This is necessary because line numbers must match exactly,
	but sed does not try to match a2 until after a1 has matched,
	yet a1,a2 where a2 <= a1 is defined to be equivelent to
	a1,a1+1

Sat Feb 29 10:55:54 1992  David J. MacKenzie  (djm@nutrimat)

	* sed.c (usage): Document long options as starting with `--'.

Mon Dec  9 23:56:40 1991  David J. MacKenzie  (djm at wookumz.gnu.ai.mit.edu)

	* sed.c: Include sys/types.h, for new regex.h.

Tue Nov  5 02:16:01 1991  David J. MacKenzie  (djm at wookumz.gnu.ai.mit.edu)

	* utils.c: Change NO_VFPRINTF to VPRINTF_MISSING, for
	compatibility with autoconf.

Mon Sep  2 22:02:40 1991  David J. MacKenzie  (djm at apple-gunkies)

	* sed.c (compile_regex): Treat \ as a normal character when in
	a char class.

Thu Aug  8 00:15:33 1991  David J. MacKenzie  (djm at bleen)

	* Version 1.08.

	* sed.c (compile_filename): If reading a file fails, read
	/dev/null instead.  It's what Unix and POSIX do, effectively.

	* sed.c (compile_regex): The 'slash' character doesn't
	terminate the regex if it's in a character class.

	* sed.c (main): If given no args, or bad option, print usage
	message.
	(usage): New function.

	* sed.c (execute_program): Amount written for 'P' command was
	wrong.  From stephend@ksr.com (Stephen Davis).

Wed Aug  7 16:51:14 1991  David J. MacKenzie  (djm at apple-gunkies)

	* sed.c (append_pattern_space): Check for buffer full before
	instead of after writing to buffer.  Don't need to test for
	EOF initially anymore, due to the next change.
	(execute_program): For 'n' and 'N' commands, if eof is reached
	in input, quit the script like Unix sed does.
	Fix memory allocation problems for 'a' and 'r' commands.
	(compile_program): Fix off by one error in processing comments.
	All of the above are from Tapani Tarvainen, tarvaine@tukki.jyu.fi.

	* sed.c (setup_jump): Use isblank instead of testing for ' '
	or '\t', for POSIX locales.

	* utils.c (ck_strdup): Renamed from strdup.
	* sed.c: Change callers.

	* sed.c, utils.c: Clean up declarations and includes to get
	rid of compiler warnings.

	* sed.c (main): Add long-named options.  Don't complain if -n
	is given twice.

Fri Aug  2 12:33:16 1991  David J. MacKenzie  (djm at apple-gunkies)

	* configure: Support +srcdir arg.  Create config.status and
	remove it and Makefile if interrupted while creating them.
	* Makefile.in: Change DESTDIR to prefix.

Mon Jul 15 13:07:39 1991  David J. MacKenzie  (djm at wookumz.gnu.ai.mit.edu)

	* sed.c (main): Add -V option to print version number.
	(USAGE): Mention -V.

Mon Jul  8 01:42:22 1991  David J. MacKenzie  (djm at geech.gnu.ai.mit.edu)

	* sed.c: Define bcopy in terms of memcpy if STDC_HEADERS as
	well as if USG.
	(compile_filename): Don't glob filename (for 'r' and 'w'
	commands).  Unix sed doesn't do it and it's not very useful,
	since it can only match 0 or 1 files.
	(execute_program): Change '\a' to 007 since some compilers
	don't recognize \a.
	* utils.c: New file; code moved from sed.c.
	* Replace Makefile with Makefile.in and configure.
	Update README.

Tue Mar 26 13:00:48 EST 1991	Jay Fenlason (hack@gnu.ai.mit.edu)

	* sed.c (match_address)  Added a trivial cast for portability.

Mon Feb 25 13:23:29 EST 1991	Jay Fenlason (hack@ai.mit.edu)

	* sed.c  Changed 's' command to work with latest version of regex()
	routines, which mysteriously changed somewhere in there. . .
	A one-line patch from David Eckelkamp (eckelkamp@mcc.com).

	Initialize the fastmap in the hopes that it'll make sed faster.

Thu Feb 21 13:42:27 EST 1991	Jay Fenlason (hack@ai.mti.edu)

	* sed.c Change panic to compile with other __STDC__ compilers.

Wed Jan 30 10:46:38 EST 1991	Jay Fenlason (hack@ai.mit.edu)

	* sed.c  Changed version number.  Made new release.

Tue Nov 27 15:34:51 EST 1990	Jay Fenlason (hack@ai.mit.edu)

	* sed.c (setup_jump)  Don't blow chunks if there isn't a label
	after a b or t command.

		(main) Don't panic if it a branch command doesn't have
	a label to branch to.

		(main)  Collect all the -e arguments together and parse them
	all at once.  This way, -e { -e mumble -e } will work.

	All these small patches from David Schmidt (davids@isc-br.isc-br.com)

Tue Sep 11 12:51:37 EDT 1990	Jay Fenlason (hack@ai.mit.edu)

	* sed.c Changed some function forward declarations to use VOID *
	instead of char *

Mon Jul 16 11:12:54 EDT 1990 Jay Fenlason (hack@ai.mit.edu)

	* sed.c (ck_malloc)  Use malloc(1) instead of malloc(0) if given
	a request for zero bytes.

Tue Jun  5 02:05:37 1990  David J. MacKenzie  (djm at albert.ai.mit.edu)

	* sed.c: Remove excess newlines from calls to panic.
	Reformat some comments to fit in 79 columns.
	Base whether to use void * on __STDC__, not __GNU__.
	(main): Add missing arg when printing usage message.
	Print usage if given invalid arg.
	(panic) [__STDC__]: Add missing ", ...".
	(compile_filename): Print correct error message if glob_filename
	returns NULL.

Thu Apr  5 21:41:12 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)

	* sed.c (execute_program, case 'r'): When need to realloc append.text,
	multiply append.alloc by 2 instead of adding
