There is a discussion on whether redisplay-dont-pause is a user option
or not, and what other choices we have for separating the implications
on sit-for vs. users who don't want the preemptive redisplay jumpiness
on slow computers.

We do have a problem/bug here ...  the question is how to solve it.

The above implementation of redisplay-now does not solve this problem,
but some form of redisplay-now function detached from
redisplay-dont-pause could be a solution.

For emacs 22, what about just making (sit-for t) force an immediate
display update, and in general let sit-for _not_ pay attention to
redisplay-dont-pause?  And update the docs/NEWS accordingly.
