The decision whether redisplay is skipped or not is based on the input-pending-p at the beginning of the command, i.e. before the call to move_it. So, if move_it triggers jit-lock which triggers font-lock, that means jit-lock found (during move_it) that input-pending-p was nil, which should imply that input-pending-p was also nil at the beginning of the command, and hence the next redisplay will not be skipped. > It's hard to say, but I'm almost sure I sometimes indeed see a small > part of the scrolling window, near its beginning, fontified.
