title: Can TextMate show tab vs space characters?
body: <p>Using TextMate on Mac, the "invisibles" can be displayed by using</p>
  
  <pre><code>View -&gt; Show Invisibles
  </code></pre>
  
  <p>But the space vs tab characters are not shown, and Preferences doesn't seem to have any entry to change that either.  Is there a way to show them?  It is because some older coder may have tab or space mixed together so what looks good in the editor may actually be misaligned. (editor shows tab as 2 spaces)</p>
