title: filetype on or filetype off?
body: <p>I use the <code>Pathogen</code> plugin for <code>gvim</code>. When configuring I set the following in my <code>vimrc</code> file:</p>
  
  <pre><code>call pathogen#infect()
  call pathogen#helptags()
  call pathogen#runtime_append_all_bundles()
  
  filetype on  "force reloading *after* pathogen loaded
  </code></pre>
  
  <p>Now I'm following <strong><a href="http://www.youtube.com/watch?v=YhqsjUUHj6g" rel="noreferrer">this tutorial on Youtube</a></strong> by Martin Brochhaus to set up Vim to be useful for Python coding and he suggests the following:</p>
  
  <pre><code>filetype off
  filetype plugin indent on
  syntax on 
  </code></pre>
  
  <p>So currently I have <code>filetype on</code> for pathogen but he is suggesting <code>filetype off</code>. What does this line of code do and how should I configure <code>vimrc</code> so Pathogen and Python are both happy? </p>
