[PATCH 03/14] was about a similar topic and explained itself a lot
better.

Even though it hinted as if it may be incomplete by saying "some" in the
subject, it was clear from the description that it consistently renamed
all the "name"s that are about references, not just "some" randomly chosen
ones. It would have been better if the subject did not say "some" to avoid
such implications.

Please give similar love to these sha1[] object names in this patch.
