title: vim: reverse foreground and background colors for colorcolumn
body: <p>Is there a way to tell vim to reverse the fore and background colors it is currently using?  For example, I have <code>colorcolumn</code> set to 101, which currently just changes the background of the 101st column to white.  The issue is it doesn't change the foreground color, so when the foreground is white or yellow or some other light color, I can't see the character in the 101st column.  I'm wondering if instead <code>colorcolumn</code> can be set to reverse the foreground and background colors of whatever text is in the 101st column.</p>
  
  <p>Alternatively, can <code>colorcolumn</code> be set to simply draw a 1px white line between columns 100 and 101, </p>
