title: How to fetch all git history after I clone the repo with `--depth 1`?
body: <p>There is a big repo with thousands of commits. When I clone it, I just want to see the latest code, and don't wait for too long, so I run:</p>
  
  <pre><code>git clone git://..../... --depth 1
  </code></pre>
  
  <p>But later, I want to see all the history commits, but I don't know how to fetch all the histories.</p>
