The fix for bug 9712, which involved changing the make-init-lua.pl perl script to handle the new C-code define names for filetypes in release 1.11, unfortunately also stopped matching against the timestamp define names. Arguably the timestamp ones should never have been matched to begin with, at least not by the same regex function, because they're not "filetypes". But they've been matched and exported into the Lua table forever, so we'll break backward-compat if we don't keep doing it. Ugh. The good news is I caught this bug using a new test script I wrote which verifies previous release's Lua stuff didn't disappear. I'll submit that separately when I get a chance to clean it up, hopefully next week.
