title: How to git blame a directory
body: <p>I would like to know how to use git blame to know who created a single directory.</p>
  
  <p>When I try:</p>
  
  <pre><code>git blame DIRECTORY_NAME
  </code></pre>
  
  <p>I get:</p>
  
  <pre><code>fatal: no such path DIRECTORY_NAME in HEAD
  </code></pre>
  
  <p>Incidentally, the directory is empty. Any suggestions?</p>
