title: Pressing tab in HTML files in vim goes to the next empty tag pair rather than expanding a completion
body: <p>I'm not sure where the functionality of tabbing to the next empty tag pair in HTML files comes from. I would like to disable it completely.</p>
  
  <p>The problem only comes with using SuperTab and SnipMate together, if I remove SuperTab tab goes back to expanding normally, if I remove SnipMate, tab goes back to showing completions.</p>
  
  <p>In the past I've had both working fine and would like to do so again.</p>
  
  <p>I'm using:</p>
  
  <pre><code>http://github.com/msanders/snipmate.vim
  http://github.com/scrooloose/snipmate-snippets
  http://github.com/ervandew/supertab
  </code></pre>
  
  <p>With vim-update-bundles. Default configuration for both. Other options I have enabled are syntax on. autoindent. smartindent. expandtab. nocompatible. filetype indent plugin on.</p>
