title: Rename a committed to branch in Mercurial
body: <p>Mercurial - What are the steps involved to accomplish the rename of a branch after it has been created and committed to (both locally and in the central repo).</p>
  
  <p>For example, I've created a branch called Zelda and then committed and pushed to a central repository. I now want to change the name of the branch to Triforce.</p>
  
  <p>Is there an extension that accomplishes this? What might be the long way in addition to any extension solution?</p>
