	per GNU Standards.

Thu May  4 23:15:58 1995  Jim Meyering  (meyering@comco.com)

Thu Apr 13 23:22:57 1995  Jim Meyering  (meyering@comco.com)

	* head.c: Remove block of redundant comments describing options.
	(usage): Remove reference to -l option.  It's not valid.

	* wc.c (wc): Don't overcount the number of bytes when reading
	from a regular file on stdin with file pointer not at BOF.
	From Karl Heuer <karl@gnu.ai.mit.edu>.  Before, the command
	`(dd ibs=99k skip=1; wc -c) < /etc/group' made wc wrongly output
	the size of the file.  Now it outputs `0'.

	not bcopy.
	(AC_CHECK_FUNCS): Add strchr and strrchr.

Tue Jan 24 22:18:19 1995  Jim Meyering  (meyering@comco.com)

	* fmt.c (copy_rest): Replace `||' with `&&'.  Before, a paragraph
	not followed by a newline would be followed by data copied from
	uninitialized storage.  Repeat by `printf abc|fmt|od -ac'.
	Reported by Franc,ois Pinard.

	* od.c: Rename macros with FP_ prefix.  Use FLOAT_ instead.
	AIX-2.2.1 declares a typedef, FP_DOUBLE, that conflicted.
	Be careful to use off_t instead of explicit `unsigned long'.
	Otherwise, systems like 4.4BSD lose on calls to fseek that
	expect off_t (which is long long on that system).
	(parse_old_offset): Use xstrtoul
	(main): Likewise.

	* src/Makefile.in (od.o, tail.o): Depend on ../lib/strtol.h.

Mon Dec 19 22:13:55 1994  Jim Meyering  (meyering@comco.com)

	* tail.c (numerous functions): Give char* filename arguments the
	const attribute.

	no corresponding argument.

	* src/*.c: Include "error.h" instead of simply declaring
	`void error ();'.
	* od.c (main): Use %lu, not %d for unsigned long.
	(my_strtoul, uint_fatal_error): Remove functions.  Use xstrtoul
	and STRTOL_FATAL_ERROR instead.

Sun Dec 11 17:24:09 1994  Jim Meyering  (meyering@comco.com)

	* sort.c (main): Fix interpretation of field offsets when specified
	via -k option.  They were being interpreted as zero-indexed.  POSIX
	says they are 1-based indices.  From Rik Faith <faith@cs.unc.edu>.
	(keycompare): Don't ignore characters at the end of words when
	otherwise they would compare equal.  From Rik Faith.

	* tail.c (<most functions>): Change the type of n_units/n_lines/n_bytes
	to off_t because n_bytes is used as the option to fseek and off_t may
	be long long (e.g. on BSD4.4).  The only place where a 32-bit limit is
	imposed is in the string-to-integer converstion of xstrtol.
	(main): Use xstrtol instead of manual string to integer conversion.

	* csplit.c (get_format_width, get_format_prec): Use ISDIGIT instead of
	comparisons against '0' and '9'.

	* tr.c [!ULONGMAX]: Define it.
	[!LONGMAX]: Define in terms of ULONGMAX instead of as a 32-bit constant.

	* full-write.c: Declare (or not) errno based on definedness or
	errno, not STDC_HEADERS.
	* safe-read.c: Likewise.
	* xwrite.c: Likewise.

Thu Nov 17 06:37:33 1994  Jim Meyering  (meyering@comco.com)

	* tail.c (dump_remainder): Flush standard output just before
	sleeping so that `tail -f' will output partial lines sooner.
	This applies only when following the end of a single file.
	From Leonard N. Zubkoff <lnz@dandelion.com>.

	* tail.c (file_lines, pipe_lines, pipe_bytes, start_bytes,
	start_lines, dump_remainder): Use STDOUT_FILENO instead of `1' in
	XWRITE calls.
	* tac.c (output): Use STDOUT_FILENO instead of `1' in xwrite call.
	* system.h (STDIN_FILENO, STDOUT_FILENO, STDERR_FILENO): Define if
	not already defined.

Wed Nov 16 07:01:38 1994  Jim Meyering  (meyering@comco.com)

	* tr.c: Include <getopt.h> instead of "getopt.h".

	* sort.c (tempname): Merge two very similar sprintf stmts into one.

	* tail.c: Use BUFSIZ instead of BUFSIZE.

	* cut.c: Declare DELIM to be `int' rather than unsigned char.

	Reported by Kaveh Ghazi.
	Always include <config.h>.
	(main): Include program name in --version output.

Sun Nov 06 00:17:21 1994  Jim Meyering  (meyering@comco.com)

	* Version 1.11.

Sat Nov 05 15:14:44 1994  Jim Meyering  (meyering@comco.com)

	* memcmp.c, srtoul.c: Use up-to-date versions.
	Reported by Franc,ois Pinard.

	* src/Makefile.in (DEFS): Remove -Dlint... again.

	* src/Makefile.in (PROGS): Add fmt!
	Reported by Andreas Stolcke (stolcke@ICSI.Berkeley.EDU).

Fri Nov 04 17:26:16 1994  Jim Meyering  (meyering@comco.com)

	* Version 1.10.

Thu Nov 03 23:23:08 1994  Jim Meyering  (meyering@comco.com)

	* linebuffer.h: Use __P instead of _P since the latter conflicts
	with a definition in some <ctype.h>.  From Kaveh Ghazi.

Wed Nov 02 17:36:34 1994  Jim Meyering  (meyering@comco.com)

	* tr.c: Add const attribute where appropriate.

	* tail.c (BUFSIZ): Use definition from <stdio.h>.

Tue Nov 01 23:54:09 1994  Jim Meyering  (meyering@comco.com)

	* tail.c (XWRITE): Allow n_bytes == 0 but call fwrite only if
	n_bytes is positive.  Turn off assertions.  `tail /dev/null' was
	getting a failed assertion.  Reported by Doug McLaren
	(dougmc@comco.com).

	* cut.c (cut_bytes): Print at least a newline for every line of input.
	(cut_fields): Print a newline even for lines whose only selected
	field is empty.  But print nothing when using -s without -f1.
	And print nothing for empty input.  Reported by
	Richard_Sharman@software.mitel.com.

Tue Nov 01 06:05:23 1994  Jim Meyering  (meyering@comco.com)

Mon Oct 31 06:53:32 1994  Jim Meyering  (meyering@comco.com)

	* configure.in (AC_REPLACE_FUNCS): Remove memcmp since AC_FUNC_MEMCMP
	already handles it.  From Kaveh Ghazi.

	* {lib,src}/Makefile.in (DEFS): Don't use -Dlint.  Some systems
	get failures when it's defined.  From Kaveh Ghazi.

	* cat.c (cat): Conditionalize test for errno == ENOSYS.  It's not
	defined on some Next and Alliant systems.  From Kaveh Ghazi.

	* sort.c join.c (main): Include version.h and call parse_long_options
	with the proper number of arguments.  Reported by Franc,ois Pinard.

Sun Oct 30 01:30:41 1994  Jim Meyering  (meyering@comco.com)

	* (configure.in): Add AC_OFF_T and rearrange by type along the

	textutils, and sh-utils will get ChangeLog entries only in the
	sh-utils.

Tue Oct 04 20:42:46 1994  Jim Meyering  (meyering@comco.com)

	* od.c (my_strtoul): Set errno to zero before calling strtoul.
	Otherwise, od can fail complaining about a valid integer argument.
	From Andreas Schwab.

Sun Oct 02 17:57:09 1994  Jim Meyering  (meyering@comco.com)

	* tr.c (main): Give an error and fail when squeezing repeats
	and no non-options are given.  Reported by Tony Robinson
	(ajr@eng.cam.ac.uk).

	* sort.c (main): Temporarily copy each input file that might be
	another name for the output file.  When in doubt (e.g. a pipe),
	copy.  This allows the dangerous (historical -- in cnews) idiom
	`cat file | sort -o file' to work properly.  Don't rely on this
	behavior in new shell scripts.  From Paul Eggert (eggert@twinsun.com).

Mon Sep 26 18:01:47 1994  David J. MacKenzie  (djm@churchy.gnu.ai.mit.edu)

Sun Apr 24 10:54:08 1994  Jim Meyering  (meyering@comco.com)

	* configure.in [AC_SIZEOF_TYPE]: Update for autoconf-1.9.
	* memchr.c: Test SIZEOF_LONG instead of LONG_64_BITS.

Mon Apr 11 17:55:52 1994  Jim Meyering  (meyering@comco.com)

	explicit error message for too many arguments.

Fri Mar 25 18:11:19 1994  Jim Meyering  (meyering@comco.com)

	* configure.in: Use AC_VERBOSE, AC_CHECKING, and AC_WARN instead
	of explicit echo commands.
	[INSTALL]: When AC_PROG_INSTALL resorts to setting this to
	`./install.sh', make it `../install.sh' instead since that
	script will be invoked only from subdirectories.
	[AC_SIZEOF_TYPE]: Use this instead of deprecated AC_LONG_64_BITS.

	* cat.c (cat): The command `:|cat -s' failed on Irix5 because
	ioctl (d, FIONREAD,... now returns ENOSYS for pipes -- under Irix4
	it returned EINVAL.  Detect this.
	(main) [lint]: Initialize variables to suppress `used before
	initialized' warnings.

	* csplit.c: Change long option name from --suffix to --suffix-format.

	* od.c (skip): Correct a comment.
	(main): Don't output anything to stdout if the sole input file
	doesn't exist.  Reported by Bauke Jan Douma <bjd@dds.hacktic.nl>.

	LDFLAGS and CFLAGS.

Wed Jan 18 16:14:00 1994  Jim Meyering  (meyering@comco.com)

	* unexpand.c (unexpand): Don't segfault when given a name of a
	nonexistent file.

	Both from Bauke Jan Douma <bjd@dds.hacktic.nl>.

Thu Jan 13 17:27:38 1994  Jim Meyering  (meyering@comco.com)

	* src/Makefile.in: Change all link commands to use both $(CFLAGS)
	and $(LDFLAGS).

	* csplit.c (load_buffer): Rather than incrementing buffer size,
	double it each time we fail to find a newline.  Otherwise, csplit

Mon Jan 10 01:20:38 1994  Jim Meyering  (meyering@comco.com)

	* man/Makefile.in (manprefix): Use binprefix as the default.

	* memcmp.c: Use the latest version from the GNU C library.

	* cut.c [ADD_RANGE_PAIR]: New macro.
	(set_fields): Collect the list of all selected ranges before
	allocating and initializing the boolean lookup table.
	(cut_bytes, cut_fields): Complete rewrite.  Avoid copying
	into buffer whenever possible.  Properly handle input without
	trailing newline.
	(getstr): New function.  Copied from getline.c, but with minor changes.

	* sort.c (main): Properly handle -Tdir.
	Before, `sort -T/var/tmp' gave `sort: unrecognized option `-v''.
	Reported by Kristoffer Rose (kris@diku.dk).

	* cut.c (main): Give separate errors for `-s without -f'
	and `-d without -f'.
	(main): Now -d '' means `use the NUL byte as the delimiter'.
	Before, it got an error.

Mon Dec 20 23:29:30 1993  Jim Meyering  (meyering@comco.com)

	* configure.in [test for 8-bit clean memcmp]: Add a test to detect
	losing memcmp from SunOS4.1.x.  From Robert H. de Vries

Sat Dec 18 01:12:24 1993  Jim Meyering  (meyering@comco.com)

	* configure.in (AC_OUTPUT): Put `touch stamp-config' in second arg
	so it goes in config.status.  This eliminates unnecessary second run
	of configure.

Thu Dec 02 23:53:03 1993  Jim Meyering  (meyering@comco.com)

	* configure.in (AC_HAVE_FUNCS): Add isascii.
	* system.h [!defined (isascii) || defined (STDC_HEADERS)]: This failed
	on AIX PS/2 1.3 systems because isascii is a function and it is used
	in definitions (with the necessary side effect of assigning to a
	global variable) of the is* macros.  Also test HAVE_ISASCII and
	redefine ISASCII(c) instead of isascii.
	Reported by Minh Tran-Le (tranle@intellicorp.com).

Fri Nov 19 22:41:48 1993  Jim Meyering  (meyering@comco.com)

	 already know we'll be using our replacement.

Fri Nov 12 00:44:49 1993  Jim Meyering  (meyering@comco.com)

	* Version 1.9.1.

	* tac.c (usage): Fix typo in long usage.
	* sort.c (usage): Likewise.
	From Philippe.Schnoebelen@imag.fr.

	* cut.c [FATAL_ERROR]: New macro.
	(main): Call both error and usage (2) through FATAL_ERROR in
	many places.  Before, only `error (2...' was called.
	(invalid_list): Removed.  This function is subsumed by FATAL_ERROR.

	* cut.c (cut_fields): Properly handle input lacking a terminating
	newline.  Before, the command  `printf "a\tb" |cut -f 1' generated
	no output.

Tue Nov 09 17:26:25 1993  Jim Meyering  (meyering@comco.com)

	od.c (usage): Change --backward-compatible to --traditional in
	the long usage message.

Sat Nov 06 22:51:31 1993  Jim Meyering  (meyering@comco.com)

	* cut.c (cut_fields): Revert July 27 change.  Instead, strip off
	trailing delimiter unless given a range of fields like `3-' that
	extends to end of line.
	(set_fields): Moved local `eol_range_start' to file-scope.
	Reported by Arne H. Juul (arnej@solan.unit.no).

Tue Nov 02 00:53:41 1993  Jim Meyering  (meyering@comco.com)

	* fold.c (fold_file): Don't get stuck in an endless loop when

	split.c, tac.c, tail.c, unexpand.c, uniq.c: Use the preferred
	`--longopt=arg' syntax in --help message rather than `--longopt arg'.
	From Francois Pinard.

	* tail.c: Don't include <signal.h>.  It hasn't been necessary
	since the Dec 12, 1992 change.

	* join.c (main): Accept `-v 1' again.  Adding the --version
	long option had broken it, although -v1 still worked.  Call
	parse_long_options instead of adding "help" and "version"
	to join's longopt strct.
	* Makefile.in [SOURCES, OBJECTS, DISTFILES]: Add long-options.c
	and long-options.h.

	From Ronald F. Guilmette (rfg@netcom.com).

	* csplit.1: Updated.
	From Ronald F. Guilmette.
	
	* csplit.c: Remove register keyword (replace with `int' in two cases).

	* csplit.c: [MAX]: Macro renamed from max and moved to top of file.

	* src/*.c: Print version on standard output, not stderr.

	* configure.in: Add AC_LONG_64_BITS.
	* memchr.c: Use #ifdef LONG_64_BITS instead of
	`if (sizeof(longword) > 4)'.

Tue Jul 27 22:19:39 1993  Jim Meyering  (meyering@comco.com)

	* cat.c (cat): Don't fail just because ioctl (d, FIONREAD,... can't
	always handle devices.  Ignore errno == EINVAL and errno == ENODEV.
	`cat -v /dev/null' was failing on many systems.

	* cut.c (cut_fields): Don't strip off trailing delimiter e.g.
	`echo 'a:b:c:' | cut -d: -f3-' should print `c:', not just `c'.
	From William Dowling <will@franklin.com>.

Fri May 21 22:57:53 1993  Jim Meyering  (meyering@comco.com)

	* pr.c (cols_ready_to_print): New function.  It replaces a global
	variable by the same name and computes on the fly the value that
	was supposed to be maintained through that variable.  This should
	put to rest the `pr -2a' bug.
	(main): Don't let getopt_long reorder arguments so we can
	distinguish between `pr -1 -2' and `pr -12'.  Rework handling of
	-n and +n options.

	* fold.c: Declare xmalloc.

Wed May 19 19:12:18 1993  Karl Berry  (karl@owl.hq.ileaf.com)

	* sum.1: Make documentation agree with the code.

	* od.c: Depend only on HAVE_LONG_DOUBLE for long double support.

	definition.  Remove unnecessary conjunct from test for hexadecimal
	prefix.

	* od.c: Depend on __GNUC__ || HAVE_LONG_DOUBLE rather than __STDC__

	indicate hex.

	* Makefile.in (dist): Depend on Makefile so that changes to
	Makefile.in (like adding new files to DISTRIB) are reflected
	in the new distribution.

Fri Apr 23 21:53:47 1993  Jim Meyering  (meyering@comco.com)

	* {lib,src}/Makefile.in [.c.o]: Make CPPFLAGS and CFLAGS follow
	other options so users can use them to override DEFS.
	* src/Makefile.in [.c.o]: Add -I$(srcdir) for version.h.

	* Makefile.in [CFLAGS, LDFLAGS]: Don't set to -g explicitely;
	configure's AC_SUBST will set these.

	* Makefile.in [Makefile]: Add dependencies and a rule to remake it.
	[targets that cd then run make in subdirectories]: Don't depend
	on `cd ..';  use a subshell instead.

	the system's doesn't grok the 8th bit.
	* memcmp.c: Fix it so it groks the 8th bit.
	TODO: We really need to provide a fast memcmp, since most
	machines will have a broken memcmp.  Probably should get
	the one from glibc.
	* sort.c (mergefps): Maintain keybeg and keylim when copying
	the current line to `saved'.
	(numcompare): Skip white space here since -n no longer implies -b.
	(getmonth): Skip white space here since -M no longer implies -b.
	(compare): Completely overhauled to make the 8th bit work right,
	also to properly handle the global reverse option.
	(set_ordering): -n no longer implies -b, according to Posix.
	For consistency, -M also no longer implies -b.
	(main): Correct treatment of -r and global keys.
	(findlines): Clear keybeg and keylim if no keys are used.

	(print_page): Rewrite conditional (that had side effects in second
	conjunct) using nested if statements to make it clear that we do
	indeed want those semantics.
