PATCH: _mh; handling of mail etc. completion

[Peter Stephenson <pws@xxxxxxx>]

Here are some minor tweaks for _mh which handle the new MH system better.

I copied the bit for mhmail (a drop-in replacement for Berkeley mail) from
_mutt.  But it seems to me completion regarding mail and associated things
has been a bit forgotten about (certainly by me).  It's fairly minor,
though; most people probably don't do this from the command line much.

- There are no completions for standard mail programmes or common
  tools like elm and pine.
- There is no special handling user@domain instead of user@host.  This
  can be done with contexts, but maybe it would be nicer to have some
  special mail _user_at_host handling which allows pws@xxxxxxx (where
  csr.com doesn't appear in my normal hosts list for obvious reasons).
