title: Is it possible to reopen a closed branch in Mercurial?
body: <p>I understand that it is possible to close a named branch in Mercurial, so that it will not appear in the <code>hg branches</code> list:</p>
  
  <pre><code>hg commit --close-branch -m 'close badbranch, this approach never worked'
  </code></pre>
  
  <p>Is it possible to later re-open the branch if need be?</p>
