title: git push --set-upstream vs --set-upstream-to
body: <p>according to this <a href="https://gist.github.com/miku/613ccf7a7030a6f32df1" rel="noreferrer">article</a>, <code>git push --set-upstream</code> is deprecated and <code>git push --set-upstream-to</code> should be used instead.</p>
  
  <p>But when I checked the <a href="https://git-scm.com/docs/git-push" rel="noreferrer">git push</a> documentation, I can only find <code>--set-upstream</code>, but <code>--set-upstream-to</code> is no where to be found. </p>
  
  <p>So is <code>--set-upstream</code> deprecated? Should I use <code>--set-upstream</code> or <code>--set-upstream-to</code>?</p>
