title: Unable to set syntax highlighting automatically in Vim
body: <p>I have the following in my .vimrc</p>
  
  <pre><code>syntax on
  filetype plugin indent on       # Thanks to Jeremy
  </code></pre>
  
  <p>I run</p>
  
  <pre><code>vim ~/.vimrc
  </code></pre>
  
  <p>I get the right syntax highlighting.</p>
  
  <p>I source many files in my .vimrc. My .vimrc is a like a roadmap for me where I navigate by</p>
  
  <pre><code>CTRL-W f
  </code></pre>
  
  <p>The problem occurs when I navigate to a file which I have sourced: <strong>no colors</strong>.</p>
  
  <p>All my sourced files contain the word Vim in their PATHs.
  It may be possible to use this fact in solving the problem.</p>
  
  <p><strong>How can you provide a syntax highlighting automatically for the sourced files?</strong></p>
