[PATCH] format-patch: use the diff options for the cover letter, too

Earlier, when you called "git format-patch --cover-letter -M", the
diffstat in the cover letter would not inherit the "-M".  Now it does.

While at it, add a few "|| break" statements in the test's loops;
otherwise, breakages inside the loops would not be caught.

	Voila.

	I thought that the changes in the for loops do not merit an own
	patch, but if you think otherwise, let me know, and I'll resend.
