title: Does GitHub consider .mailmap for contribution graph
body: <p>Have got a git repo with incorrect contributors and their contributions. Repo has few commit's from different emails and alias name and we have added <code>.mailmap</code> to resolve this issue.</p>
  <p>Shortlog recognizes <code>.mailmap</code> and groups contributions accordingly, but it doesn't reflect on GitHub. Does GitHub consider <code>.mailmap</code> file or should we have to wait for GitHub re-run the graph.</p>
  <pre class="lang-sh prettyprint-override"><code>git shortlog -sne
  </code></pre>
  <p>Note: We have waited for 24 hours already</p>
