	* msg.tcl: 
	Labelled algorithm choices as stable and unstable.

	* msort.c:

	Separated the tests whose success depends on locales
	from the rest. The main set are run by "make test" as before.
	To run the locale-dependent tests, type "make localetest".

	* msort.c:
	Made error-checking and reporting finer-grained in GetMonthNames.
	
	Split time and iso8601 date/time regression tests so as not to
	mix data with and without time zone offsets since mixing them causes
	tests to fail if executed in some time zones.

	Release of version 8.50.
	
	* msort.c: 
	Fixed bug in which compound positional keys (those involving portions of more
	than one field) were not properly null terminated, resulting in various sorts
	of errors, including crashes. 

	Key specifications with a character offset of zero are now treated
	as fatal errors and reported to the user.

	* configure.ac: 
	Changed AC_FUNC_MALLOC in configure.ac to AC_CHECK_FUNCS([...malloc...])

	of comparisons.

2007-01-09  Bill Poser  <poser@khunekcho.khunek.poser.org>
	Version 8.35 released.
	
	* msort.c (main): 
	Added checks to several key-specific options to ensure that a key has
	been specified earlier on the command line. This eliminates segfaults
	when such incorrect command-lines are encountered. All key-specific
	options are now covered. For some reason this check was missing
	from a few of them. Also made error message more informative and
	moved the check into a function.

	* Makefile.am (AM_LDFLAGS):

2006-12-17  Bill Poser  <poser@khunekcho.khunek.poser.org>
	* msort.c sorts.c: 
	Fixed subtle bug in multigraph mapping (MapNonHybridLI).
	
	Redid the handling of non-locale-dependent hybrid keys,
	which required modifications of both Compare and
	GetKeys. This eliminates occasional, apparently random,
	segfaults.

	If there is only one record, we still mention that there
	is no point in sorting only one record but we now
	exit successfully after writing out that record.
	This is necessary for non-interactive use.

2006-07-06  Bill Poser  <poser@khunekyaz.khunek.poser.org>

	* input.c strs.c:
	Modified to use new prefixed UTF8 error codes.

	which corrects record numbers output with error messages. 
	
	*passim:
	Sorted out configuration conditions into three groups, LOCALE_SORT_ORDER,
	LOCALE_MONTH_NAME, and LOCALE_GETTEXT, so that we now check for just
	the right combinations.
	
2006-04-28  Bill Poser  <poser@S010600023f310f85.ca.shawcable.net>
	Added options for treating certain classes of characters as their "basic" counterparts:
	      (a) strip diacritics;
              (b) treat enclosed characters as basic.
              (c) treat stylistic variants as basic.
	      	  At present this includes the stylistic variants of the ASCII characters,
	  	  the Latin but non-ASCII symbols, the Arabic positional variants,
	  	  the half-width CJK punctuation, the half-width kana, and the half-width

2006-03-09  Bill Poser  <poser@S010600e0185aee1a.ca.shawcable.net>

	* msort.c: 
	In atofwc now strip space characters so as to prevent
	strto(l)d from reporting an error due to, e.g., a newline
	following the number when records are not lines and fields
	are not lines.

2006-03-05  Bill Poser  <poser@S010600e0185aee1a.ca.shawcable.net>

	* configure.ac: 
	Added check for libtre so that absence will be detected prior to

2006-02-25  Bill Poser  <poser@S010600e0185aee1a.ca.shawcable.net>
	passim:
	Added option of numeric string comparison.
	
2006-02-17  Bill Poser  <poser@S010600e0185aee1a.ca.shawcable.net>
	passim:
	
	Key selection by position has been extended to allow keys to span
	contiguous fields from one position to another, where a position
	consists of a field number and a character offset. This makes key
	selection by position approximately the same as in GNU sort. One
	difference is that unlike GNU sort, msort permits field numbers to be
	negative, indicating a count from the end. The other is that in msort
	if only a single position is specified only that field is included in
	the key, whereas in GNU sort the key extends from the specified
	position to the end of the record.
	

2006-02-11  Bill Poser  <poser@S010600e0185aee1a.ca.shawcable.net>

2006-02-05  Bill Poser  <poser@S010600e0185aee1a.ca.shawcable.net>

	* msort.c: 
	Moved the four sort functions, ancillary routines, and Compare
	into sorts.c This required moving some definitions out of msort.c
	into header files, including the creation of comparisons.h and keys.h.

	* info.c:
	Added command line option for fixed length records to option summary.
	
	* msort.c: 
	Added support for fixed length records.

	Fixed bug that added extra newlines to output.

	* msort.c (main): 
	Added check of whether input is restricted to BMP if -B option is specified.
	
	Added choice of algorithm, and added Mergesort and InsertionSort as possible algorithms.
	
	Also added a configure option --(dis|en)able-allocaok, which controls
	whether alloca is used in Mergesort. By default it is, but storage may be
	allocated on the heap instead if alloca is buggy, as it is on some systems.
	
2006-01-17  Bill Poser  <poser@S010600e0185aee1a.ca.shawcable.net>

	* msort.c misc.c record.h:

	* msort.c (GetKeys): 
	Now check the conversion of numeric strings to internal floats for errors.
	Fixed bug in which msort segfaulted if given a very long  numeric string
	as key.

  Fixed bug in DescribeKeys when sorting on whole record. 

1994-02-08 Bill Poser version 4.11
  Now allow numeric key field specification to be negative,

  Now allocate MapTable dynamically, when needed, saving a fair
  amount of space when a key does not use any multigraphs.
  Added log entries regarding dynamic memory usage. 
  Now allocate numeric keys dynamically. This makes numeric comparisons
  very slightly slower and wastes 4 bytes per record per key for numeric
  keys, but it saves 4 bytes per record per key for textual keys,
  which are far more common in the intended applications of this
  program. 

1993-12-21 Bill Poser version 4.9
  Reserved highest rank table slot for default key, reducing
    number of multigraphs permitted by one.
  Added copy of command line to log.

   buggy and not worth fixing since the speedup was so small.
   Now use quicksort instead of shellsort for large numbers of records.
   Added -a flag to warn that input is almost in order, in which case
   shellsort is used for any number of records. 
   Also changed report of time per record to integral milliseconds. 

1993-10-28  Bill Poser version 4.4
   Replaced lexicographic keys with ranks.

1993-10-27  Bill Poser version 4.3

   Changed max record flag to -M so as to use -R for this.

1993-07-05  Bill Poser version 4.2
   Made key code type compile time option. If only 7-bit ASCII
   input is desired and 128 multigraphs are sufficient, msort can
   be compiled with SEVENBIT defined and will use half the space for
   textual keys. 

1993-07-04  Bill Poser version 4.1
   Modified format of elapsed time report and moved into library functions.

1993-06-26 Bill Poser version 4.0
