bug#8284: 24.0.50; M-q badly bound in diff-mode

[Julien Danjou]

Hi there,

The `diff-mode' keymap `diff-mode-shared-map' inherit from
`special-mode-map' which defines M-q as `quit-window'.

This is *very* annoying when editing diff file build with
git-format-patch. I sometimes add some text/comments in it, and press
M-q to run `fill-paragraph'. But this calls `quit-window' and pisses me
off.

I don't know what is the best way to fix this, therefore I'm not
including any patch in this report, but would do it if possible. :-)
