There is some extensive work done by Cyrille Lefevre, and which
was sent in as a PR.  I have incorporated some of that work, and
plan to incorporate more of it.  (although probably not in the
exact manner that Cyrille wrote it up).  I also have a few updates
of my own for `ps', that I need to clean up and commit.  I was
doing work in May and June.  In July I got bogged down with some
other matters, and I have not gotten back to `ps' since then, but
I do intend to get back to it once 5.3-release is official.

At least some of the changes are incompatible with our present `ps'
command, so we can't just throw them in and break the behavior that
FreeBSD users are used to.  For instance, `-G' is already in our
version of `ps' which is in the 5.x-branch, due to work done earlier
this year.  `-A' is also supported, but it is (deliberately) not
documented.  The *code* for `-g' is also in our source, but it is
commented out because it conflicts with the historical definition
of `-g' (which has always been supported in FreeBSD, so many people
are used to typing it).
