Subject: git-notify: Handle non-UTF-8 commits

Make sure that commit messages which use an encoding other than US-ASCII
or UTF-8 are handled correctly.  Also, assume that the diff contents use
the same encoding as the commit message.  This assumption may well be
wrong, but that's the best we can do.
