This is pretty low-priority and I don't think it needs to be
MFC'd for the 4.4 release, but there is a small error in ps's
old-style option handling. An outstanding example of this is
when one runs `ps Uroot':
$ ps Uroot
ps: rooT: no such user
ps: No users specified
The problem is that the function ps.c:kludge_oldps_options()
capitalizes any 't' at the end of the option string, regardless
of whether it's a flag or an option argument. The patch attached
to this message should fix the problem.
