When whitespace-mode is enabled and the buffer is scrolled such that
only part of a long line is visible at the top of the buffer, it becomes
impossible to scroll the window down using the down arrow.
This can be reproduced from ‘emacs -Q’ with
C-u 99 <return>
M-<
C-u 99 a
C-u 0 C-l
M-x whitespace-mode
followed by pushing <down> until the window scrolls (it won’t!).

I can reproduce this in Emacs 23.2, but not in Emacs 24.0.50.
