exchange: make narrow ACL presence imply narrow=True

And refactor the logic for determining when to invoke our custom
changegroup part function so it is only conditional on
narrow being set. This makes it more obvious under which
conditions we should invoke the custom implementation.

Also use raw strings so **kwargs works on Python 3.
