This is a bug. If the destination side of a refspec is omitted, and the
source side resolves to a ref starting with "refs/heads/" or
"refs/tags/" (which I expect it does here), then that ref is used as the
destination.

I submitted a patch at [0], but it was decided not to pick it up. If
Junio and the list decide that it's wanted, I'm happy to resend or
revise and resend.
