Thanks for the offer. I really need to get down and spend a few hours
investigating. I've elp'd CC Mode, and tried M-> (2 seconds) followed
by <PgUp> (13 seconds), and it looks like
c-append-lower-brace-pair-to-state-cache is taking up the time. It
seems it is being called too often. Maybe.
Maybe I'll pin it down at the weekend.
