This does too many things in a single patch.

Ideally this would have been four patches for reviewability:

 - one "trivial and obviously correct bits" (s/remote/remote_name/ and
   removal of sort_string_list(&branch_list)) patch;

 - the change for states->{new,tracked}, should stand on its own; I think
   the reordering of the output should be described much better and
   defended independently.  "Earlier it was sorted by this order, which
   did not make sense for such and such reasons; this fixes the logic to
   sort the list by the name of the tracked branch, which makes it easier
   to read", or something like that.

 - change to the states->tracked population rule; and

 - get_ref_states() to lose the util bit.

It probably is Ok to squash the last two, though.
