It's no problem -- I'll just add a `mm-handle-raw-content' accessor,
and store the raw contents where they can be got at.

Right.

I would imagine that we would add some encoding handlers for MIME
encryption that would force mml to encode using qp, no matter what.
There's no such thing in there yet, but I don't think it would be
difficult to add stuff like that.
