Interesting.  Yeah, this shouldn't happen.

What is the exact command you use to get the above output?  Is your
repository public (which would let us reproduce it) or can you
reproduce it by creating a small artificial test repository?

For comparison, did some previous version of git work ok in the same
scenario, or is this the first time you've tried it?

Thanks,
