While it's unusual to have strange files in loose object database,
.git/objects/pack/tmp_* is normal after a broken fetch and they
can eat up a lot of disk space if the user does not pay attention.
Report them.

The hook in prepare_packed_git_one is ugly, but I don't want to
duplicate the search file logic there in count-objects. Maybe I'm
wrong.
Interestingly it reports .commits file in my repo too. A nice
reminder to myself to remind Jeff about count-objects improvements
for his commit-cache work :)
Way may also need a more friendly format than this one, which I
assume is plumbing. Something that average git user can understand
without looking up the document. If "git stats" is too much for this
purpose, perhaps "git gc --stats"?
