Hmm, it might not be the right fix after all.  

It does fix the utf-8 editing problem, and I think also another problem
that someone reported in gnu.emacs.gnus about utf-8 format=flowed
messages being mangled.

*But* it introduces \201's in message/rfc822-forwarding of non-ascii
messages :-(  

Hmm, is the " *mm*"-buffer associated with a MIME-handle supposed to be
unibyte or multibyte?
