title: vimrc import file
body: <p>I have a repository of my home config files - <a href="http://hg.jackleo.info/home-configs" rel="noreferrer">http://hg.jackleo.info/home-configs</a></p>
  
  <p>I noticed that my vim configuration is getting bigger and bigger (90% of commits is only related to vim) so I want to trow it to separate repository.</p>
  
  <p>The problem is that since i'm using home-config repository at my actual home folder vimrc file is also in same place. If I would include subrepo to Vim configuration (folder .vim) I couldn't commit .vimrc file to that sub-repository.</p>
  
  <p>Is there a way to simply write <code>import file_path_to_other_config</code> and hold exact configuration in .vim folder?</p>
