With the testcase one can demonstrate the problems with scrolling very
well by moving point to the start of the buffer and typing `C-u 1 C-v'
a few times.  The first time the buffer will be scrolled correctly.
The second time all overlays will disappear and point will move to the
third window line.  The third time the overlays will appear again and
point will be put right after the first overlay.  After that you can
type `C-u 1 C-v' as often as you want and nothing will happen anymore,
especially no scrolling.  I tested this in an Emacs checked out and
compiled today and started with `emacs -Q'.
