	output device.  Otherwise, there are too many loops, and we get a
	stack overflow because of recursion.

2008-10-05  Stephen Gildea  <http://www.gildea.com/stephen/>

	* src/preproc/ref/ref.cpp (reference::compute_sort_key): Do

	also.
	(!!c): New macro for comments.
	(rm): New traced macro.
	(de, de1, am, am1): Use \\[xxx]\\ calling method to pass \$0 to
	`!!xxx'; this makes doc.tmac completely traceable.
	Trace call of .de and friends also.

	* tmac/groff_tmac.man, NEWS: Update.

2008-09-30  Werner LEMBERG  <wl@gnu.org>

	Restore behaviour of \$0 if a macro is called with string syntax

	  .de aaa
	  \\*[bbb]\\
	  .  tm \\$*
	  ..
	  .de bbb
	  .  shift
	  ..
	  .aaa 1 2 3

	* contrib/pic2graph, contrib/pic2graph.man, contrib/eqn2graph,
	contrib/eqn2graph.man: Tweak scripts to cope with incompatible
	changes in ImageMagick crop options.  Document the bugs.

2008-09-28  Werner LEMBERG  <wl@gnu.org>

	If a macro is called as a string, inherit value of \n[.br] from the
	caller.  This is useful for `trace.tmac'.

	* src/roff/troff/input.cpp (string_iterator): New members

	(string_iterator::string_iterator): Updated.

2008-09-24  Werner LEMBERG  <wl@gnu.org>

	Fix incompatibility between `.de1' and `.do'.  Without this change,
	the following snippet

	  .de1 xx
	  .  tm \\n(.C
	  ..
	  .cp 1
	  .do xx

	prints 1 instead of 0.

	* src/roff/troff/input.cc (do_request): If a macro gets processed,
	call tok.next().
	(interpolate_macro): Add optional argument.  Update callers.
	(request::invoke): Add optional argument.
	(macro::invoke): Add optional argument to delay call of tok.next().

	by Denis M. Wilson.

	* tmac/www.tmac (.EQ, .EN, .TS, .TE): Fix definitions.

2008-07-24  Denis M. Wilson  <dmw@oxytropis.plus.com>

	* src/preproc/tbl/tbl.man: Minor improvements.

2008-05-02  Larry Jones  <lawrence.jones@siemens.com>

	* contrib/chem/Makefile.sub (README, examples/README): In makefiles,
	the `$<' macro is only guaranteed to be defined in inference rules,
	not in explicit target rules.  Since there is only one input file in
	the places where it is used, the `$?' macro (which is guaranteed to be
	defined for both kinds of rules) is a suitable replacement.

	* hdtbl/examples/fonts_n.in, hdtbl/examples/fonts_n.in: Most
	versions of ls don't have a `--color' option.

2008-04-05  Dorai Sitaram  <ds26gte@yahoo.com>

	Add better support for `.TAG #<label>' in non-HTML documents: In
	case of a forward reference in a call to .URL, write `(see below)'.
	In case of a backwards reference use the page number instead.  The
	reference gets stored in a string `TAG_<label>' and can be
	overridden while calling `.TAG' with its new optional argument --
	this is useful for a second-pass system which resolves forward
	references.

	* tmac/www.tmac (www:url_check_tag): New function.
	(URL): Use it.
	(TAG): Add optional argument to define string `TAG_<label>'.

2008-03-24  Werner LEMBERG  <wl@gnu.org>

	* tmac/trace.tmac (so, mso): Added.

	* tmac/www.tmac (PIMG): Replace `.ie' (without `.el') with `.if'.
	If used with -mtrace, and this clause was active, the macro was
	executed twice.

	* tmac/pspic.tmac (PSPIC): Accept option `-C' for orthogonality.
	This makes `.PIMG -C <file>' (from www.tmac) work on non-HTML
	devices.
	* man/groff_tmac.man: Document it.

2008-02-26  Werner LEMBERG  <wl@gnu.org>

	* src/roff/troff/input.cpp: s/safer_flag/unsafe_flag/.
	Update all occurrences so that \n[.U] works as advertised.  Bug

	yet.  This happens, for example, in this situation:

	  .ft I
	  x x
	  (\,f

	Add support for MathML output to eqn.

	The strategy used is very simple and relies on the fact that the box
	models of eqn and Presentation MathML differ in only trivial ways.
	It leaves the grammar and existing internal object structures
	unchanged.  A new global, `output_format', is defined as an
	enumerated type with values {troff, mathml}.  Most of the functions
	and methods that emit actual output acquire a top-level conditional,
	dispatching on this global, which has one arm for troff mode and one
	for MathML mode.  In most cases the MathML arm is drastically
	simpler.

	(This strategy could be easily generalized to support other output
	formats.  TeX is a possibility that leaps to mind.)

	The only even moderately tricky changes are in the lexer.  Some of
	the predefined macros used constructs like `up', `down', `fwd',
	`back', and `vcenter' that have no equivalents in MathML.  I
	attacked this problem in these ways:

	1. I eliminated three uses of `back' to compose characters in favor
	   of using equivalent groff specials `\(<<', `\(>>', and `\(<>'
	   that did not exist when these macros were written.  (This will be
	   a quality improvement for troff users.)

	2. I eliminated one use of `vcenter' by using \\(md.  (Likewise...)

	3. I then split the table of pre-definitions in three; one large
	   common table and two small troff-specific and MathML-specific
	   tables.  Use of troff-only operations (up, down, back, fwd,
	   vcenter) is now confined to the former.  The latter now uses
	   `size big' and drops out the explicit positioning operations,
	   counting on MathML processors to do them.

	POTENTIAL TROUBLE SPOTS:

	Here are notes for reviewers on places I'm not 100% sure I've done
	the right thing:

	* In the process of preparing the troff table, I translated three
	  definitions (dot_def, dotdot_def, and utilde def) that previously
	  used explicit \v escapes to use `up' and `down' instead.  I
	  modeled the new definitions on the way `vec' and `dyad' work, but
	  it's possible I got something subtle wrong.

	* I'm not certain the MathML implementation of font_box::output() is
	  right, because I don't quite get what the switcheroo between
	  `current_roman_font' and `old_roman_font' is supposed to
	  accomplish.  It does seem to generare good MathML, though.

	Finally, I made one purely cosmetic change in `text.cpp'; I replaced
	with an enum some magic numbers for spacing types that I thought
	were too ugly to live.

	REMAINING ISSUES:

	The entirety of eqn is translated when `-TMathML' is specified,
	with the following exceptions...

	Limitations that cannot be fixed include non-support for special,
	up/down/fwd/back, and vcenter.

	Limitations that might be fixable include non-support for mark and
	lineup.  I will investigate further, but if these can be implemented
	at all it's going to be in a very complicated and nasty way.

	The way character boxes are output means that each digit of a
	multi-digit number gets its own <mn></mn> tag pair in the MathHTML.
	While this is not technically wrong for Presentation MathML, it is
	ugly and inefficient.  Fixing this will require implementing a
	little state machine in the `text.cpp' output method.
