title: Vim expand all blocks by default
body: <p>I'm using the awesome spf13 Vim distribution,
  when I open a code file I find collapsed all the blocks,
  so I usually do a <code>zE</code> to expand all the blocks,
  beacuse I like that way ..</p>
  
  <p>is there some trick to do this automatically on every file?</p>
