Or it makes you add

 (add-hook 'diff-mode-hook (lambda () (setq show-trailing-whitespace nil)))

to your .emacs if it really bothers you. This is not "to turn off the
alarm mechanism", but rather than having it activated for patches is a
mistake, because patches are not text (as David has said).

Again, I agree with David: I've installed quite a few patches, and
I've never reported back problems with them if I could trivially fix
them. Lack of complains is not a positive proof.
