Thsi patch prepares for a proposed change in RFC4880bis to support a
MIME flag.  A literal data packet with the mime flag set is handled
like a 't' or 'u' but CR are not removed.  The PLAINTEXT status line
will also indicate a MIME content.

If --mimemode is used without --rfc4880bis 't' will be used.
