title: Why is vim reading system zipPlugin.vim after reading my .vimrc file?
body: <p>I have a line </p>
  
  <pre><code>set cpoptions+=$
  </code></pre>
  
  <p>in <a href="https://github.com/xiaotian/dotfiles/blob/master/vimrc" rel="nofollow">my .vimrc</a> file. However according to </p>
  
  <pre><code>verbose set cpoptions output:
  
  cpoptions=aABceFs
  Last set from /usr/share/vim/vim73/plugin/zipPlugin.vim
  </code></pre>
  
  <p>: it is always overridden by zipPlugin.vim. I am wondering why is vim reading these plugins <strong>after</strong> reading my <code>.vimrc</code> file? Any way to fix this?</p>
