title: Git stash: "Cannot apply to a dirty working tree, please stage your changes"
body: <p>I am trying to apply changes I stashed earlier with <code>git stash pop</code> and get the message:</p>
  
  <pre><code>Cannot apply to a dirty working tree, please stage your changes
  </code></pre>
  
  <p>Any suggestion on how to deal with that?</p>
