Pass -M to diff in request-pull

Linus recommended this, otherwise any renames cause the
diffstat output to be ridiculous in some circumstances.

Because the corresponding "git-pull" done when the requestee
actually makes pull shows the stat with rename detection
enabled, it makes sense to match what the request message
includes to that output, to make the result easier to verify.
