2a1fb74048 touch.1: Update to conform to POSIX 2004
POSIX borrowed the "double leap second" bug from C89.  Double leap seconds can
never happen.  This mistake was present in at least POSIX 1997 and fixed by
POSIX 2004.  I can't find a copy of 2001 online to determine if the bug was
present in that revision.

While here, remove duplicate language between -d and -t.  A few other minor
enhancements and an igor (lint) bugfix.

fbbd9655e5 Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

587714504f touch: Add the -d option from POSIX.1-2008.
This is much like -t but with a different format which is ISO8601-like and
allows fractions of a second.

The precision is limited to microseconds because of utimes() and friends,
even though stat() returns nanoseconds.

401c9fda42 Remove useless and potentially dangerous rw() function which tries to
update access and modification times by reading and writing the file.
chmod(2) in rw() doesn't help because utimes(2) allow owner and the
super-user to change times. Using just utimes(2) should be sufficient.

The -f option becomes no-op.

3be5f1f5ce Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

     .\"    $Id$
     .\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.
