Subject: [PATCH 15/16] scripts/get_maintainer.pl: Add -f directory use
Date: Mon, 13 Jul 2009 14:15:01 -0700

Don't require a specific file in a directory
to be tested.

Also Arnd Bergmann pointed out that the MAINTAINERS
pattern requirement that directory patterns have a
trailing slash was unnecessary and was likely to be
error prone.  Removed that requirement.
