Indeed, real bug, but ps.c is only about 75% complete. It doesn't
implement "ps ax" yet, or distinguish between dash vs non-dash options.
(That's why I haven't tested the corner cases yet. This is probably the
command that's going to force me to make a run as root aboriginal linux
test case build control image, because I need to control the PID numbers
to get reproducible results...)

I'm writing up release notes as we speak. I've got a half-dozen pending
commits but there's _always_ a half dozen pending commits, so I need to
snapshot and move on and then have the next release more quickly.
