(format "%04d-%s.patch"
  (or (notmuch-wash-subject-to-patch-sequence-number subject) 1)
  (notmuch-wash-subject-to-filename subject 52))

or something would be more lispy.

Clicking on the button for the part saves the wrong thing, though,
because it's not a real MIME part. That looks a bit awkward to fix, so
perhaps you could still prefix the name with "inline: " to indicate that
it's odd?

Otherwise, looks good.
