title: Ambiguous Names with GIT?
body: <p>I'm trying to check out one of my local branches, named TEAM20-lab2-release.  When I try to do this, I get an ambiguous refname error:</p>
  
  <pre><code>$ git branch TEAM20-lab2-release
  warning: refname 'TEAM20-lab1-release' is ambiguous.
  fatal: Ambiguous object name: 'TEAM20-lab1-release'.
  </code></pre>
  
  <p>Here is the list of my branches:</p>
  
  <pre><code>$ git branch -a
    TEAM20-lab1
  * TEAM20-lab1-release
    master
    remotes/origin/HEAD -&gt; origin/master
    remotes/origin/master
  </code></pre>
