unpack-trees: rewrap a few overlong lines from previous patch

The previous patch made many lines a little longer, resulting in four
becoming a bit too long.  They were left as-is for the previous patch
to facilitate reviewers verifying that we were just adding "internal."
in a bunch of places, but rewrap them now.
