And a patch description

once you fix those issues, patch looks fine and should be OK for merging.
i'll pick it up if Wolfgang doesnt, but it should be OK to merge for this
release.

(Patch now includes signed-off-by and description. Sorry, I'm still picking
up git's e-mail flow.)

if you're sending out a patch or two and the patches themselves have an
adequate changelog, then you dont need to send out a summary e-mail too.
should save you some time in the future.
