Thanks.  This is indeed very similar to what Martin presented,
i.e. forward-line moves point outside of the window, and then
redisplay returns point back into the view.  But since the change that
fixed Martin's case doesn't fix this one, I guess some other place in
the code is setting the force_start flag of the window.

I will look into this.
