Short refs are accepted and expanded at the server side with expand_ref= () because we cannot expand (unknown) refs from the client side. Like deepen-since, deepen-not cannot be used with deepen. But deepen-no= t can be mixed with deepen-since. The result is exactly how you do the command "git rev-list --since=3D... --not ref".
