[PATCH repost] Multiple refs from the same remote in one git fetch

["Michael S. Tsirkin" <mst@xxxxxxxxxxxxxx>]

Hi, Junio!
Is the following likely to get merged eventually?
It was pointed out that I can work-around the limitation
by using softlinks, so it's not a show-stopper for me.

---

Fix git fetch for when multiple refspecs reference the same remote head.
