* doc/bison.texi: Use @kbd where appropriate.
Update ^~~~ marks for caret-errors.
* build-aux/cross-options.pl: Do not add quotes to %define's argument.
This change was made by applying emacs' untabify function to
nearly all files in Bison's repository. Required tabs in make
files, ChangeLog, regexps, and test code were manually skipped.
Other notable exceptions and changes are listed below.
* bootstrap: Skip because we sync this with gnulib.
* data/m4sugar/foreach.m4
* data/m4sugar/m4sugar.m4: Skip because we sync these with
Autoconf.
* djgpp: Skip because I don't know how to test djgpp properly, and
this code appears to be unmaintained anyway.
* README-hacking (Hacking): Specify that tabs should be avoided
where not required.
* build-aux/cross-options.pl: As in --help output, write optional
arguments as [=ARG] not =[ARG].
* doc/bison.texinfo (Bison Options): Add -W/--warnings argument.
* doc/bison.texinfo (-g, -x): Add space before argument.
(Option Cross Key): Implement FIXME: listing directives also.
* build-aux/cross-options.pl: Read from <STDIN> rather than <>.
(Short Option): Special case -d. Put arguments inside @option.
(Bison Directive): Add column, automatically extracted from
src/scan-gram.l (actual name passed as the first argument)
with special case for %define.
* doc/local.mk (doc/cross-options.texi): Pass src/scan-gram.l
to build-aux/cross-options.pl.
* src/getargs.c (usage): Document limitations of cross-options.pl.
* src/scan-gram.l: Likewise.
* build-aux/cross-options.pl: The argument ends at the first
space, not the first non-symbol character.
Use @var for each word appearing the argument description.
-g and -x take optional arguments, just like their long options.
* build-aux/cross-options.pl: Use /x to make the regexp easier to
understand.
Fix the handling of $opt which resulted in all the argument to be
considered as optional.
* NEWS (2.3a+): Mention.
* doc/bison.texinfo (Bison Options): Add an entry.
* src/files.c (compute_output_file_names): Don't override
spec_verbose_file if already set.
* src/getargs.c (usage): Document --report-file.
(REPORT_FILE_OPTION): New anonymous enum member.
(long_options): Add entry for it.
(getargs): Add case for it setting spec_verbose_file.
* build-aux/cross-options.pl: Don't record a short option just because
there's an arg.
* doc/.cvsignore: Add yacc.1.
