This 90% is for CC-mode, where font-lock is particularly expensive. > And second, the 2nd redisplay will only redraw the portions that were > fontified, not the entire window. So this is not "twice", but more > like 1.2 times. The 1st redisplay also only redrew the portion that was modified, which is pretty close in many cases to the portion that later gets fontified.
