Where did this patch come from? Signed-off-by Stefan Schmidt ? If he
wrote it, then it needs to have
From: Name <email>
as the first line of the long description so that git-am will credit him
as the author. git format-patch will generate that for you if he's the
author and you export that commit from git.
Other than that, this patch looks like a good idea.
Alan.
