dffc24ecb5 xargs: fix parsing of empty fields when "xargs -0" is used.

d7259957e8 userspace: remove vestigial '?' cases from top-level getopt(3) loops 
getopt(3) returns '?' when it encounters a flag not present in the in
the optstring or if a flag is missing its option argument.  We can
handle this case with the "default" failure case with no loss of
legibility.  Hence, remove all the redundant "case '?':" lines.

Prompted by dlg@.  With help from dlg@ and millert@.

d3a07ef22e Delete support for LC_MESSAGES which we shall never implement. 
This nicely simplifies the code, deleting three header inclusions
and calls to various complicated library functions.

Dead code reported by Jan Stary <hans at stare dot cz>.

Garbage collect pointless (void) casts and a .Tn macro while here.

f02859560d pledge "stdio rpath proc exec". proc & exec because obviously it 
spawns subprocesses.  rpath is only needed for the -o (open /dev/tty)
or no -o (open /dev/null) choice.

b9fc9a728f Replace <sys/param.h> with <limits.h> and other less dirty headers where 
possible.  Annotate <sys/param.h> lines with their current reasons.  Switch
to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc.  Change
MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where
sensible to avoid pulling in the pollution.  These are the files confirmed
through binary verification.

b7f5ef4233 Regarding -L, consider a line ending in unescaped white space and the next 
non-empty line to form one single line, as required by XPG 4.
While here, use isblank(3) to identify white space instead of assuming
that only blank and tab are white space characters.

Geoff Clare <gwc at opengroup dot org> agrees that the standard for -L
should say "A line is considered to end with the first <newline>
unless the last character of the line is an *unescaped* <blank>;
an *unescaped* trailing <blank> signals continuation to the next
non-empty line, inclusive."  The word *unescaped* is missing from
the standard, but we regard that as a goof in the standard.

Bug noticed by, much feedback from, and "should go in now"  guenther@

043fbe51c1 rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and 
unmaintainable).  these days, people use source.  these id's do not provide
