```
$ git branch --track branch master
Branch branch set up to track local branch master.
$ git branch -m master newmaster
$ git branch -vv
  branch    e8fadc2 [master] foo
* newmaster e8fadc2 foo

I would have expected branch's upstream to now be newmaster rather
than master, or at the very least some warning that branch now has a
nonexistent upstream. Is this intended behavior, or a bug?

I think "branch -m A B" moves everything in "branch.A.*" over to
"branch.B.*" and does nothing else.

You would also want to find all Cs that have "branch.C.merge = A"
and "branch.C.remote = ." and update A in them to B, or something.
