title: Modifying the "proof" completion (environment based on current word) in TextMate LaTeX bundle
body: <p>Editing with the TextMate LaTeX bundle, I'm trying to change the behaviour of the "Environment based on current word" snippet when applied to the "proof" environment. I would like it to behave as a normal (i.e. not a labeled) environment. 
  I edited the bundle configuration file (Bundles --> LaTeX --> Edit Configuration File). I deleted the lines</p>
  
  <pre><code>proof = {
          triggers = ( pf, proof );
                      content = "\\label{pf:$1}\n\t$0";
      };  
  </code></pre>
  
  <p>(from the labeled_environments section)
  and added the lines</p>
  
  <pre><code>proof = {
          triggers = ( pf, proof );
      };  
  </code></pre>
  
  <p>to the environments section. 
  Upon application -- typing pf and command-{ -- I now get two choices, both called "proof", with the first behaving as I wish and the second behaving as it used to (i.e. the labeled version). 
  Is there a way to get rid of the second?</p>
