argh, so a fix for a serious regression has been languishing in the
backwaters of the rtc list for two weeks.

Guys, please: regressions are serious, top-priority emergencies. We
drop everything and run around with our hair on fire when we hear about
one (don't we?). Please, if you have a report of a regression or a fix
for one, Cc: everyone in the world on it.

I'd prefer not to go fishing through HTML to piece that patch together,
but as my hair is on fire I guess I'd better do so.
