title: how to know the depth of a git's shallow clone?
body: <p>If I retrieve a shallow clone, e.g.</p>
  
  <pre><code>git clone --depth 10 http://foo.bar/baz.git
  </code></pre>
  
  <p>Does <code>git</code> have any command to retrieve the depth of this clone? (e.g. a command that simply prints <code>10</code>).</p>
