title: Silence only status output after checkout
body: <p>I want to provide my own custom coloured git status via a <code>post-checkout</code> hook.</p>
  
  <p>How can I disable the default monochrome short status output that is displayed after checking out a branch?</p>
  
  <p>I only want to disable the status part (so I don't print it twice), but I want to keep other messsages such as:</p>
  
  <pre><code>Already on 'master'
  </code></pre>
  
  <hr>
  
  <p>Alternatively, if there's no way of only disabling the short status output, is there a way to force all <code>checkout</code>s to be <code>--quiet</code>?</p>
  
  <p>I want to avoid double status outputs under all circumstances.</p>
