title: Vim 'Project' plugin - "Not enough room" when performing a project-wide grep
body: <p>The extremely useful "Project" plugin offers a project-wide grep via shortcuts <code>\g \G</code>. When I try to use this on a project of reasonable size, I receive output:</p>
  
  <pre><code>Error detected while processing function &lt;SNR&gt;20_GrepAll
  line 21:
  Not enough room.
  </code></pre>
  
  <p>I've searched vim help for a solution and haven't come up with anything thus far.</p>
  
  <p>Does anyone know the cause of this, and whether there's a quick remedy available, perhaps via some option in my .vimrc?</p>
