title: Can't track remote branch - doesn't recognize origin/develop
body: <p>I have git 1.8.3 and a repo with 'master' and 'develop' branches.</p>
  
  <p>From my local 'develop' branch, I'm trying to do the following command - </p>
  
  <p><code>git branch -u origin/develop</code></p>
  
  <p>and I get an error of</p>
  
  <p><code>error: the requested upstream branch 'origin/develop' does not exist</code></p>
  
  <p>When I check <code>git branch -r</code> I see only <code>origin/master</code></p>
  
  <p>I'm trying to find a way to make my system recognize that there is also a <code>origin/develop</code> and can't find any solution that works.</p>
