title: git : give me the repo, nuke everything local, I don't care
body: <p>Does git have any pull/checkout 'nuclear option' to get the repo?
  I don't care about any conflicts, I don't need any of my local stuff, 
  just want the goods so I can work.</p>
  
  <p>[edit]
  to clarify my issues:</p>
  
  <pre><code>$ git pull
  error: Your local changes to the following files would be overwritten by merge:
  
  &lt;...files I couldn't care less about...&gt;
  
  Please, commit your changes or stash them before you can merge.
  error: The following untracked working tree files would be overwritten by merge:
  
  &lt;...more files I couldn't care less about...&gt;
