Scrolling down with down arrow get stuck in a loop in some positions.
Cursor goes down to the bottom of the screem, but then the cursor jumps
up some lines. The page is not scrolled down as it should be. The cursor
is stuck in this loop.
To reproduce this start with
emacs -Q
then open the attached file (vline.el) and do
M-x eval-buffer
M-x vline-mode
M-x viper
<down-arrow>
Just hold <down-arrow> down and the bug will eventually show up. To make
it easier to see what happens you can reduce frame height first.
