makes `yes' exit unsuccessfully.
(chroot invocation): Enumerate the meaning of exit status values.
(nice invocation): Likewise.
(Exit status) [@macro exitstatus]: New macro.
Use @exitstatus to describe the exit status of most programs.
global variables.
(collapse_escapes): Rewrite to set globals rather than modifying
its parameter.
Use size_t (not int) for all counters and related index variables.
(paste_parallel): Remove needless complexity of
using xrealloc in the loop; just allocate the buffers up front.
Free the two temporary buffers.
Move declarations of locals `down' into scope where used.
(paste_serial): Remove `register' attributes.
(main): Simplify delim-related code.
Free `delims', now that it's malloc'd.
remnant) from PATH component. That would cause tests in this directory
not to run the just-built binaries, but rather whatever happened
to be in one's PATH. Reported by Christian Krackowizer.
(CHROOT_FOUND_BUT_CANNOT_INVOKE, CHROOT_FAILURE): Define.
(main): Exit with status of 127, not 1, for too-few-args,
chroot failure, or chdir failure.
Give a better diagnostic upon execvp failure.
(obsolete_usage): New var.
(longopts): Put obsolete options first.
(OBSOLETE_LONG_OPTIONS): New constant.
(get_option, add_file_name): New functions.
(main): Use them to support new behavior.
(usage): Remove documentation for -j1 FIELD and -j2 FIELD.
Do not mark -j FIELD as obsolescent; it is longstanding
UNIX tradition and is a valid extension to POSIX.
size; just modify the argument, which is no longer const *.
Various other minor cleanups, mostly to avoid the need for casts.
(extract_field): Renamed from ADD_FIELD, as it's now a function.
(struct field.beg): Now char *, not unsigned char const *. All
uses changed. It shouldn't be const since xmemcoll writes on its
arguments.
(extract_field): Likewise, for 2nd arg.
(keycmp): Remove now-unnecessary cast of xmemcoll args.
(is_blank): New function, to avoid need to cast arg to unsigned char.
(extract_field): Use it.
(xfields): Rewrite pretty much from scratch.
(hard_LC_COLLATE): Now bool, not int.
(get_line, getseq, add_field_list): Now returns bool, not int.
(decode_field_spec, add_field_list): Return true on success (not
false), for consistency with the rest of the code. All uses changed.
(tab): Now char, not unsigned char. This wasn't 100% necessary
but is slightly cleaner.
(prjoin): Hoist (tab ? tab : ' ') expression, to help the compiler.
(empty_filler): Now const *.
(make_blank): Remove; wasn't needed. Remove all calls.
(main): Don't set uni_blank.nfields; zero is fine.
(min, max): Remove definitions.
Make a few function parameters and corresponding
locals `const'. Use bool for boolean variables.
Use size_t (not int) for all counters and related index variables.
(prjoin): Remove now-useless assertion.
(string_to_join_field): New function.
(main): Accept join fields as large as SIZE_MAX.
(keycmp): Rename `min' to MIN and max to MAX.
