Err, SUSv3 lists a few options that we don't implement, and some that
cross over between SysV ps and BSD ps. This is what SUSv3 says for ps:
ps [-aA][-defl][-G grouplist][-o format]...[-p proclist][-t termlist]
[-U userlist][-g grouplist][-n namelist][-u userlist]
In general, a *BSD system isn't going to support all the SysV ps
options. Should we just say as much in the manpage?
I have some patches that implement most SysV options but never have
committed them because no one could ever agree on how to choose which
style of option processsing to use...
