bug#10259: 24.0.91; C-x s d puts the point at the end of *Diff*

[ofv@wanadoo.es (Óscar Fuentes)]

emacs -Q

Visit a file which is several screenfuls long.

Make changes here and there to produce a diff large enough to not fit
into a splitted window.

C-x s d

The window splits, *Diff* is shown on the new window, but the point is
at the end of *Diff* and the user can't inspect its contents by pressing
C-M-v nor he can type `C-x o' to switch to that window nor click on it
while the prompt still is on the minibuffer. If the user wishes to
inspect the contents of *Diff*, he must exit the prompt and switch to
that buffer.

There is a trick: once the *Diff* buffer is shown, you can type `d'
again and *Diff* is correctly shown with the point at the beginning, so
C-M-v works. Anyways, C-M-v as the sole method for moving the point on
the *Diff* buffer is quite limited. On the past, it was possible to
switch to the *Diff* buffer and move around without exiting the prompt.
