Big patches

[Mark Linimon]

Sorry, I did not see your message and emailed you separately.

GNATS has a spamcatcher for > 500k messages (mostly this catches viruses).
Normally I handle such PRs manually before the cleanup process runs, but
I forgot to do it this time.  (I only took a glance.)

Does the plist change dramatically every time the ports are updated?  Is
there any way around this if so?  Such large changes put stress not only
on GNATS (it is, after all, a database), but also on the CVS repository
when the updates are committed.
