title: aligning or prettifying code in emacs
body: <p>I remember this was possible in emacs, but don't know how. If I have something like:</p>
  
  <pre>
  'abc' => 1,  
  'abcabc' =>2,  
  'abcabcabc' => 3,  
  </pre>
  
  <p>How can I align the keys, arrows and values to something like this?</p>
  
  <pre>
  'abc'       => 1,  
  'abcabc'    => 2,  
  'abcabcabc' => 3,  
  </pre>
  
  <p>Cheers</p>
