[hacknews] mail revisions

I've made some internal revisions to mail(1), mostly internal cleanup
and setting it up to use getopt(3).  The only external changes are a
better usage message when it's invoked improperly, and a -R option which
is intended to replace the kludgey business of having mail notice what
name it was called under.  The old binary is in /work/oldmail in case
of disaster.
