This almost works - patch forthcoming. The trouble with just using
notmuch-show-mm-display-part-inline is that it doesn't move the point
to the end of the text, which we rely on for message-cite-original to
quote the right region. But, I can use
notmuch-show-mm-display-part-inline (moved to the lib) by narrowing
first, and setting the point after using it. If we don't narrow, the
point ends up after the user's signature (which is inserted by message
mode before we insert the quoted text), and the signature ends up
being quoted.

Yeah, I agree with this. Maybe before 0.14 I will try to do some
refactoring to share code between reply and show, at least in emacs.
