pass upstream rev to scripts/get_maintainer.pl

["Uwe Kleine-König" <u.kleine-koenig@pengutronix.de>]

Hello,

I often face the "problem" that get_maintainer.pl yields my name, too,
as the commits I want to send are included in HEAD.

I think the nicest fix for that would be to be able to pass an upstream
rev à la:

	scripts/get_maintainer.pl --upstream linus/master ...

.  As my knowledge of perl is quite limited I only provide you with
my quick'n'dirty patch I usually use, just to give you an idea.

Best regards
Uwe
