title: hg-git: delete remote branch?
body: <p>Is it possible to delete a remote branch with <a href="http://hg-git.github.com/" rel="noreferrer">hg-git</a>?</p>
  
  <p>I can delete the tag locally (<code>hg bm -d old-branch</code>), but it's not obvious how to tell the git server to do the same.</p>
