I got around to updating my test boxes to include this and did a full
re-run and I believe you may have missed removing the newline from the
golden outputs of btrfs/006 and btrfs/101. Sorry if I missed an updated
version or something.

I don't yet see this patch in the various branches I look at, so I
assume it's not to late to fold in those two changes as well. If not,
lmk, and I'm happy to send a follow up later.

Thanks,
Boris
