title: Reopen a Pull Request
body: <ul>
  <li>I Submitted a Pull Request</li>
  <li>The PR got merged and was closed.</li>
  <li>Later for some reasons the changes were reverted</li>
  </ul>
  
  <p>Now I have been asked to create Pull Request again. I know that once a PR is closed we cannot reopen it. Now I need those PR changes in my new branch.Is there any other way to get PR commits in another branch other then <code>cherrypick</code>?  </p>
