title: Git clone --no-checkout again
body: <p>I don't want to waste space on my machine and I only want to see the history of repository (for each branch). That's why, I did a:</p>
  
  <pre><code>    git clone --no-checkout
  </code></pre>
  
  <p>After I did this, somebody pushed something. I have to do something to be again with the history updated, but I don't know what. Of course, I can use git checkout &amp; git pull, but I don't need the files, I need only the .git folder to be updated. I tried with git fetch, but it seems the history is not updated.</p>
