Patch 7.4.1837
Problem: The BufUnload event is triggered twice, when :bunload is used with
`bufhidden` set to `unload` or `delete`.
Solution: Do not trigger the event when ml_mfp is NULL. (Hirohito Higashi)

If someone questions your market projections, simply point out that your
target market is "People who are nuts" and "People who will buy any damn
thing". Nobody is going to tell you there aren't enough of those people
to go around.
