bug#2549: 23.0.60; doc-view: scrolling other window wraps unexpectedly

With p.ps from:

   http://www.logic.at/prolog/p.ps

when I do:

   $ emacs -Q p.ps

and press:

   C-c C-c C-x 2

and then press C-M-v repeatedly, the other window eventually wraps
around instead of stopping at the image border like C-v does.
