Yup.  I've now done the refactoring, so there should be no user-visible
changes for Gnus usage, and it should basically work outside of Gnus, too.

That makes sense to me, with the (perhaps obvious) caveat that calling
without binding the setup function should cleanly do the display
(perhaps with less fontification) and return.

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.

I should have been more precise. I'm calling it indirectly via
mm-display-part, which is useful in the case where someone attaches a
message/rfc822 part to their message. In principle notmuch can (and in
the general case does) render the part directly, but in certain odd
fall-back cases it is handy to give a visual representation of the part
in the buffer without parsing etc.. ourselves.  So the user does have a
mail reader, namely notmuch. In fact I can almost make it work by
forcing the buffer back into notmuch-show-mode after calling
mm-display-part, but that has some side-effects I'd prefer to avoid.

Thanks for thinking about my (weird?) use-cases,

David

Yeah, it's confusing.  `mm-inline-message' is really an "internal" Gnus
function, while most of the other mm functions are more general.

Disentangling that mess is daunting, but for that function in
particular, I guess it wouldn't be that difficult to rewrite it to avoid
doing anything Gnus-ish unless we're in Gnus...  On the other hand, it's
a function to display a complete message, which leaves you with a buffer
that's pretty pointless unless you have a mail reader to interact with
it afterwards.

So perhaps it should just be renamed and moved to Gnus?
