title: How to give up unstaged changes
body: <p>I made some changes on my local machine and I don't want to keep them.</p>
  
  <p>When I perform a <strong>pull</strong> to get the recent changes from the server I get a message saying that I have unstaged changes and I must commit or stash them.</p>
  
  <p>But I don't want to do it. I want to cancel them. How to do this?</p>
