title: Showing branch hierarchy at the command line?
body: <p>I'm curious if there is a way to show branch hierarchy on the command line? For instance if I use <code>git branch</code>, instead of seeing output like this:</p>
  
  <pre><code>* master
  joes_work
  refactoring
  experiment
  </code></pre>
  
  <p>You see output like this:</p>
  
  <pre><code>* master
      joes_work
      refactoring
          experiment
  </code></pre>
  
  <p>That way it's easy to see which branch a particular branch.. branched off of. Even if there's no specific command that outputs a tree structure, is there a command that outputs information on which branch came from which branch? I can use a perl script to format the output.</p>
