Because the arguments are matched like

	case "/$path" in
	*/$pat )

so if you have remote "refs" and refs/remote/refs/heads/x, git-ls-remote refs/heads/ is ambiguous. OTOH, --heads always match start of the path.

It's somewhat obscure and probably doesn't really matter for user interface, but API should be free even of obscure misbehaviour, I believe.
