a037e838e1 maint: Use logical rather than bitwise operators on bools 
This is because bitwise operators are:
- confusing and inconsistent in a boolean context
- non short circuiting
- brittle in C89 where bool can be an int (so > 1)

5d4f09d83a doc: mention the texinfo documentation in --help 
* src/system.h: Rename emit_bug_reporting_address() to
emit_ancillary_info() and update it to not print the translation
project address in en_* locales, and _do_ print it in the 'C'
(and other) locales so that it's included in the default man page.
Also mention how to invoke the texinfo documentation for each command.
Also move the "hard-locale.h" include to the 8 files that now use it.
* man/help2man: Strip the newly added texinfo reference from the
--help output as a more verbose version is already added by help2man.
Suggestion from C de-Avillez

45e67188d6 remove redundant const directives 
In 1463824d8e, I added some
missing "const" directives, as well as some new, redundant ones.
This removes the redundant ones.  Pointed out by Eric Blake.

Don't complain about -DIGIT.
 2005-04-26 16:41:03 +00:00

specified via the obsolete form.  E.g., now this command fails:
_POSIX2_VERSION=1 ./expand -$(echo '2^64+1'|bc)

All callers changed.
(parse_tabstops): Don't pass a negative char to isblank.
Avoid memory leak with large tab stops.
(validate_tabstops, expand): Don't assume number of tab stops is
<= INT_MAX.
(next_file, main): Use EXIT_SUCCESS/EXIT_FAILURE rather than 0/1 when
storing values into exit_status.
(expand): Use same pattern as unexpand for reading chars.
Report an error when input line is too long, instead of silently
screwing up.  Do not mishandle tab stops when backspacing left
over start of line.
 2004-08-02 23:49:31 +00:00

Update the call to parse_long_options so that `AUTHORS, NULL' are the
last parameters.

* src/true.c (main): Append NULL to version_etc argument list.

Jim Meyering
33f9d106bc Add more support for POSIX 1003.1-2001, which requires removal for

Jim Meyering
afa12bc912 (usage): Use new macros, EMIT_HELP_DESCRIPTION and EMIT_VERSION_DESCRIPTION

Jim Meyering
909dc8c01d Factor out some common strings to make translation easier. 
Split usage strings so that --help and --version descriptions are alone
