Overall I really like this series. In addition to the clean up etc it
makes it easy to export the text/plain part (which doesn't have a part
button). I have recollection of this being difficult if it is base64
encoded.

I have a few small comments

As mentioned on irc (just included here in case other people are
testing) make-composed-keymap is emacs 24 only.

This does change the default directory for saving: not serious but it's
probably worth deciding do we want to use mailcap-download-directory or
home or where emacs was started or?

I don't know if we want to keep a special keymap for the button or just
always use the . prefix; the advantage is that you don't have 's' on a
button acting differently from 's' in the text (which has annoyed me
several times) otoh it is the extra keystroke which may annoy people
too. Let the bikeshedding begin! (obviously return for the default
action would remain.

Would it be worth having . return in the part body  as the default
action ?

Finally, with message indenting it's the start/end of the part are a
little unclear. I think it's the [ of the part button at the start of
the part to the character before the [ of the next part button. In
particular on the line of a new part but before the button is still the
old part. Since parts are whole lines it would be nice if the region
were line based but I don't know if that is easy.

Best wishes
