title: What does git fetch followed by checkout FETCH_HEAD do?
body: <p>What does the following command do:</p>
  
  <pre><code>git fetch &lt;remote&gt; &lt;branch&gt; &amp;&amp; git checkout FETCH_HEAD
  </code></pre>
  
  <p>I have only one local branch (<code>master</code>) and I execute the above command. What changes to my local repository should I expect and how can I verify (see) them?</p>
