They are the deref of the thing without them.

As in, "foo" is a tag pointing at some object (probably a commit
but not necessarily) then "foo^{}" is whatever "foo"'s tag points at.

Probably could just be:

		case "$name" in
		*^{})
			continue ;;

This is common in Git.  ^{} on the end of a ref name shows up in
the peek-remote/ls-remote output, but certainly is *not* a ref.

Sorry I missed that case eariler when I reviewed the patch. I thought
about it and why it wasn't handled here, but then thought maybe it
wasn't actually occuring in the input (that someone else higher up
had filtered them out).
