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.
