title: Update git-svn list of remote branches
body: <p>When I have to use svn, I use git-svn to talk to svn. I cloned the repo with the standard git svn clone -s line, and all the remote branches at the time were there.</p>
  
  <p>Since then, a new branch has been created, but not by me. I want to checkout/track this branch locally. I can track a branch that I can see (with git branch -r) like so:</p>
  
  <pre><code>git checkout -t -b dev remotes/development
  </code></pre>
  
  <p>But this doesn't work with the other branch, since it doesn't show up in git branch -r</p>
  
  <p>How can I track this missing branch?</p>
