/*======================================================================
   Code here for forward and reply to mail
   A few support routines as well

  This code will forward and reply to MIME messages. The Alpine composer
at this time will only support non-text segments at the end of a
message so, things don't always come out as one would like. If you
always forward a message in MIME format, all will be correct.  Forwarding
of nested MULTIPART messages will work.  There's still a problem with
MULTIPART/ALTERNATIVE as the "first text part" rule doesn't allow modifying
the equivalent parts.  Ideally, we should probably such segments as a 
single attachment when forwarding/replying.  It would also be real nice to
flatten out the nesting in the composer so pieces inside can get snipped.

The evolution continues...
