That's currently a very significant requirement throughout
redisplay_window and its subroutine: any result that leaves the
current line (i.e. the line where point is) not completely visible is
rejected, and we select some other window-start point to avoid that.
It's possible to toss this requirement, of course, but then a lot of
existing code in the display engine will have to be rewritten, because
I won't be surprised if the assumption that this holds is implicitly
made by some parts of the display code.
