title: vim left and right column highlight
body: <p>I need to highlight anything beyond column 72 with a different background color.  What's the best method?  Something similar to a visible line margin that some editors do is also good.  Is it possible?</p>
  
  <p><em>Some background:</em></p>
  
  <p>The syntax is a Pascal like, and works correctly.</p>
  
  <p>Only the Background needs to change.  The foreground is already highlighted as it should be.  There are cases where a String will be more than 80 characters and will pass the 72 column limit, and should be highlighted as a string.</p>
  
  <p>The coding standards are similar to COBOL and all characters beyond column 72 <em>should</em> by comment lines.  These column 72 comments do start with the comment start character, and are highlighted properly.</p>
