Yeah, I had look at this, but it really doesn't work - you can't
_replace_ an old message, you can only add a new one to a folder.  You
can set a system-defined flag called \Answer that signifies whether or
not you've replied to a message (which I guess helps out on the "-" you
have in the scan listing), but it's a poor substitute.

Also means that things that reorder the mailbox, like "sortm" won't
be possible in the conventional sense.  And "folder -pack" is a no-op
(unless we want to forgo using IMAP message sequence numbers and simply
use UIDs and maintain a local mapping.  Icky).
