title: Make Syntastic close just the error window
body: <p>I've got the (Mac)Vim Syntastic plugin installed via Janus. When I open the <code>:Errors</code> window to view the reason for syntax errors, it shrinks the file with the errors to one line and uses the rest of the real estate for the Errors window.  </p>
  
  <p>Is there a way to make it hog less room for errors and more importantly, how do I close <em>just</em> the Errors window?  The usual <code>:q</code> closes both the Errors window AND the original file, even if the cursor is in the Errors window.  (That's not 100% correct -- it gratefully does not close the file if the file hasn't yet been saved).</p>
