Actually, due the listing of new files in the patch, the patch was so
large that it got bounced pending moderation (13K, with a 12K
limit). It's not actually as complicated as this size would make seem --
mainly just a lot of moving lines to individual files. Since I'm not
sure who the mod is, I'll take this as a sign that I should try to break
it down into smaller patches.

Sorry for the delay.
