Looks like we need a better check here. Can > we know from Content-Type if fetching a part body would be useful? What if `notmuch-show-insert-part-*/*' consulted a list of content-type regexps to attempt to inline? That would allow a sane default (("image/*" "text/*") perhaps), but also allow more to be added to that list (or some to be removed), either by code that detected the (in)ability to render it or the user.
