Subject: [BUG?] git branch -m doesn't update tracked branch config
Message-ID: <CAD0k6qRWR9H8BejcXx3gzy2yQT_MjRBDtbZzhLVM215HQiaVhg@mail.gmail.com>

$ 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?
