git branch / git checkout -b now honor --track when the upstream branch is local. Previously --track was silently ignored for local upstream branches. The configuration setting branch.autosetupmerge can now be set to "always" which is equivalent to using --track. Setting branch.autosetupmerge to boolean true will retains the former behavior of only setting up branch.*.merge for remote upstream branches.
