git config `push.default`:

  – `nothing`: do nothing (make the user say what they mean)
  – `matching`: push all local branches for which a remote branch of the same name exists
  – `upstream`: push only the current branch, push it to its upstream, making push and pull symmetric
  – `simple`: like upstream, but only if the branch names match (will become default in 2.0)
  – `current`: push just the current branch
