I run emacs 23.1.1 to get the documentation of view-mode-enter
there. So, this patch instructs to delete WINDOW when exiting
view mode...

Documentation of pop-to-buffer says:

"Select buffer BUFFER-OR-NAME in some window, preferably a different one."

What if pop-up-windows's value is nil -- the content of current window
is replaced with this view stuff -- and when exiting view mode, the
window will be deleted ? What happens with emacs 24 in this case ?
