title: How to PR and merge again after reverting PR using Github Revert Button
body: <p>Basically I used <a href="https://github.com/blog/1857-introducing-the-revert-button" rel="noreferrer">Github revert button</a> to revert a previous PR for a <strong>feature branch</strong> into <code>master</code>, then I decided to merge the same <strong>feature branch</strong> that I reverted earlier, but I was not able to do so. Steps as follow:</p>
  
  <ol>
  <li>PR to merge <strong>feature branch</strong> to <code>master</code></li>
  <li>Revert PR merge from (<code>master</code>)</li>
  <li>Tried to create new PR to merge feature branch to <code>master</code> again.</li>
  <li>Got this message:</li>
  </ol>
  
  <blockquote>
    <p>There isn't anything to compare.</p>
    
    <p>master is up to date with all commits from feature-branch. Try switching the base for your comparison.</p>
  </blockquote>
  
  <p>Any suggestions on how can I merge <strong>feature branch</strong> again into <code>master</code></p>
