When you do a `g' VM does not save the old INBOX buffer over the
disk copy of INBOX.  It appends whatever it finds in the your
spool mailbox to the disk copy of INBOX and the buffer copy of
INBOX.  Two separate operations, so the contents don't mix.  If
you hit make changes and hit `S' after the `g' then you do lose.
