Yes, that was what I was thinking about -- the rendered embedded message
can't be easily interacted with without the mail reader being able to
hook into the rendering.  I mean, it's a kinda semi-recursive thing: You
want to be able to use (some of) the mail reader's commands to respond
to the embedded message.  Which is why `mm-inline-message' calls the
Gnus functions here.

But perhaps the function should be rewritten to call a (say)
`mm-inline-message-setup-function', bound by the caller?  Then both Gnus
and notmuch could use the function.
