on NetBSD the return value may well be positive.
Use one-line aggregate initializations.
Use tightly scoped static buffers to avoid warnings about
unused variables on some systems.
permissions, but give a misleading diagnostic like this:
rm: cannot chdir from `.' to `foo': Not a directory
(remove_dir): Detect the case in which unlinking a
non-directory fails with EPERM, and give an appropriate diagnostic.
Use strspn to avoid an explicit loop.
Use fputc rather than printf "\n".
Include quote.h.
(print_stat): Use xreadlink, rather than using readlink directly.
Use the quote function rather than hard-coded double quotes.
Use error, not perror.
Add long_iso_time_style.
(time_style_args, time_style_types, decode_switches): Likewise.
(decode_switches): If a time style is prefixed by "posix-", ignore
it if in the POSIX locale. Default style is now posix-long-iso.
(usage): Explain the above.
instead of the combination of strcat and printf.
(print_statfs) [!FLASK_LINUX]: Print `*' for %S and %C, rather than `S' and `C'.
(print_stat) [!FLASK_LINUX]: Likewise.
around the problem of making the translations of the adjective
`write-protected' and the corresponding run-time-variable noun
(e.g., file, directory, symlink, etc.) consistent. From Paul Eggert.
[!HAVE_SYS_STATVFS_H && !HAVE_SYS_VFS_H]: Include sys/param.h
and sys/mount.h, to get decl of struct statfs on NetBSD 1.5.2.
(NAMEMAX_FORMAT, STRUCT_STATVFS): Define.
(HAVE_STRUCT_STATXFS_F_TYPE, SB_F_NAMEMAX): Define.
Remove `static' attribute from decl of program_name.
(human_fstype): Use f_basetype or f_fstypename if available.
(print_human_time): Use nstrftime and an ISO format string, in
place of strftime with `%c'. The latter is too locale-dependent.
(print_statfs): Deal with lots of portability issues: some fields
are available only with statfs, others only with statvfs, and
some are available in both, but with different types.
(do_statfs) [DEFAULT_FORMAT_TERSE]: Factor out.
[DEFAULT_FORMAT_VERBOSE]: Likewise.
(ID_LENGTH_MAX): Define.
(ST_DM_MODE): New macro. Code moved from...
(print_long_format): ...here.
(print_long_format): Itemize and comment the individual parts
of init_bigbuf. Use the above *_MAX macros.
