title: git add . --quiet: quiet option not available
body: <p>I've just untargzipped some code and I want to add a whole bunch of files
  at once to the repository and commit. Unfortunately git add doesn't have
  a <code>--quiet</code> flag and all that I/O to print every single file from the tarball
  is slowing things down. How can I speed this operation up (by silencing
  output from <code>git add</code>?).</p>
  
  <p>What I would like to do is:</p>
  
  <pre><code>git add . --quiet
  </code></pre>
  
  <p>Since this flag does not exist I've tried redirecting standard error:</p>
  
  <pre><code>git add . 2&amp;&gt; /dev/null
  </code></pre>
  
  <p>Unfortunately git strangely returns without adding any files when I do this.</p>
  
  <p>How can I solve the problem?</p>
  
  <p>Thanks.</p>
