Thanks.  I realized one minor oversight.  Using -p should imply -a so
that even if the PID is not owned by the current user, it will still
get listed.  I've attached a patch for this (just a one line addition)
that builds on top of the previous patch (i.e., apply it against
version 1.20 of ps.cc).  Thanks again.
