title: How to delete a specific revision of a github gist?
body: <p>I created a Gist on GitHub and I saw informations I don't want anyone to see.
  I updated the file since, but everybody can still access the old revision of the file.</p>
  
  <p>Except deleting the Gist, is there a way to delete that particular revision definitely?</p>
  
  <p>I saw that I'm not the only one having that kind of problem (<a href="https://stackoverflow.com/questions/2261031/git-delete-a-single-remote-revision">Git: delete a single remote revision</a>) but I didn't manage to remove the revision.
  The process indicated here seems to help remove some files. I want to remove the whole revision.</p>
