Configure git to push only the current branch

Push the current branch to the remote branch with same name.
push.default=matching ask git to push the current branch either:

- to the branch with the same name only when the current branch is set
  to integrate with that remote branch on the same remote;

- to the branch with the same name, when pushing to a remote
  that is not where you usually fetch from.
