Ok, I sent a reply to David's message a few minutes ago from Mutt, but
apparently that didn't go through. This one, which retracts the
complaint about the thread not expanding in WL, did.

Anyway, David, I did examine mime-preview-condition. It looked like
reasonable code that would conditionally handle various MIME types and
subtypes, though I don't really know enough lisp to know much about
it.

However, I didn't understand your suggestion about C-M-x. When I tried
this, I just got a prompt in the minibuffer.
