title: Meaning of the GitHub message: push declined due to email privacy restrictions
body: <p>I have accepted and merged a pull request on GitHub, and now I cannot pull my commits any more.</p>
  <p>The message is:</p>
  <pre><code>! [remote rejected] master -&gt; master (push declined due to email privacy restrictions)
  error: failed to push some refs to 'git@github.com:FranckFreiburger/vue-resize-sensor.git'
