These commands don't have too much to do with redisplay. Unless point
moves outside the currently displayed screen, the only aspect of
forward-* commands related to redisplay is the cursor motion, I think.
Gerd, am I right?

If you call forward-char like that, I think the only redisplay is the
last one, after you move 500,000 characters forward. So I think
redisplay is not an issue in these tests.
