My instinct would have been to do this with a temporary buffer rather
than the narrowing but I am *definitely* too much of a lisp beginner to
say that either is better.

(I think notmuch-show-mm-display-part-inline uses the temporary buffer
approach.)

Anyway, as it is, it looks correct and seems to work! (and is obviously
useful functionality)

Best wishes
