In some "simple" centralized workflows, users expect remote tracking branch names to match local branch names. "git push" pushes to the remote version/instance of the branch, and "git pull" pulls any changes to the remote branch (changes made by the same user in another place, or by other users). This expectation is supported by the push.default default option "simple" which refuses a default push for a mismatching tracking branch name, and by the new branch.autosetupmerge option, "simple", which only sets up remote tracking for same-name remote branches. When a new branch has been created by the user and has not yet been pushed (and push.default is not set to "current"), the user is prompted with a "The current branch %s has no upstream branch" error, and instructions on how to push and add tracking. This error is helpful in that following the advice once per branch "resolves" the issue for that branch forever, but inconvenient in that for the "simple" centralized workflow, this is always the right thing to do, so it would be better to just do it. Support this workflow with a new config setting, push.autoSetupRemote, which will cause a default push, when there is no remote tracking branch configured, to push to the same-name on the remote and --set-upstream. Also add a hint offering this new option when the "The current branch %s has no upstream branch" error is encountered, and add corresponding tests.
