Document date --rfc-3339 and new specifiers %:z, %::z, %:::z. Use
"date and time" consistently; the old version sometimes said "time
and date". Fix a minor bug in the documentation for --rfc-2822:
it claimed day-of-month < 10 had leading space, not leading zero.
Use a consistent format for terms like "RFC".
Mention that false is often built-in, and that it exits
with status >1 on some hosts.
(true invocation): Remove now-incorrect "non-POSIX mode" reference.
(available on MS-DOS-like platforms only). Explain when text and
binary mode are used now.
(md5sum invocation): -b actually does have an effect on Unix: it
causes "*" to be output. Explain when text and binary mode are
used now.
equivalent to --time=atime, not --time=ctime.
(ls invocation, du invocation): Fix typo: --time-style=long-iso
is equivalent to a time style with a leading "+".
(du invocation): --last-time is now --time.
--time-style no longer implies --time.
The locale and posix- stuff now works only for TIME_STYLE, not
for --time-style. Give equivalent format for --time-style=iso.
since it now works the same regardless of POSIX version.
(od invocation): -w N -> -w[N].
(pr invocation): -S STRING -> -SSTRING.
(fold invocation): -WIDTH works even when conforming to POSIX
1003.1-2001.
(head invocation, tail invocation): Likewise for -NUM.
(split invocation): Likewise for -LINES.
(uniq invocation): Likewise for -N.
(expand invocation, unexpand invocation): Likewise for -TAB.
(nice invocation): Likewise for -ADJUSTMENT.
(sort invocation): Clarify explanation of +N option.
(uniq invocation): Likewise.
(join invocation): Remove special case for --help, --version.
(touch invocation): Clarify explanation of date options.
(Options for date): -I timespec -> -I[timespec].
the point of departure for -m, and explain what it meeams.
(mkdir invocation, mkfifo invocation, mknod invocation):
The umask does not affect the point of departure.
(chgrp invocation, basename invocation, dirname invocation):
Add examples, which are copies of the examples newly added
to the usage messages.
(ln invocation): Use same format as other examples above,
for consistency.
clear tha the default date use space-padded day of month.
Replace "directive" with "conversion specifier" to be consistent
with POSIX. All uses changed.
Fix menu RHS to match actual directive lists.
(Time conversion specifiers): Renamed from Time directives.
Use @samp consistently, sometimes instead of @code.
Consistently ention which specifiers are GNU extensions.
Give more examples (in some cases, instead of ranges).
Say why %F is preferred for dates.
(Date conversion specifiers): Renamed from Date directives.
Likewise for other changes.
(Padding and other flags): Correct the description.
Document #. Give an example for %9B.
GNU extensions.
For %p and %P, mention handling of noon and midnight.
For %s, use ISO 8601, and mention handling of leap seconds.
For %S, clarify mention of leap seconds.
For %T, say that it's the same as %H:%M:%S.
For %X, don't say that it must be the same as %H:%M:%S.
For %z and %Z, clarify which time zones are used. These options
are now affected by --date, so don't claim that they're not.
(Date directives): %C is now all but the last two chars of %Y.
For %D, say that it's equivalent to %m/%d/%y.
For %e, use blank in example.
For %h, use @code for %b.
For %Y, mention what happens with outlandish years.
(Padding and other flags): Renamed from Padding.
Mention that the flags are GNU extensions.
Mention the 0 and ^ flags.
Mention field widths an modifiers.
(Examples of date): - is a flag, not a modifier.
