You should ask handa about that and other Mule issues.  Experience shows
it's not helpful for me to explain.

There were various things like that I left unfixed for Mule 6 (for
various reasons) five years ago, or whenever it was.

By the way, `undecable' should be `undecodable' in the comment, which
may only apply in Emacs 21 -- I don't know.

I think there are various things wrong with
`message-fix-before-sending'.  The one I remember is it objecting to
stuff in non-text inline MIME parts, e.g. if you try to use
application/octet-stream for a Lisp backtrace.
