Re: `y-or-n-p' does not wait for input - assumes `n'

[Richard Stallman]

    Should we avoid (let ((track-mouse t)) ...) and prefer (track-mouse ...)
    or is there a reason to sometimes use one sometimes use the other?

The difference seems to be that track-mouse can do a redisplay,
if turning off mouse-tracking means input is no longer pending.

I don't see why it does that, and I am not sure it is
ever actually desirable.  Does anyone see a case where
it is the right thing to do?
