title: How to underline (rather than highlight) the current line in vim?
body: <p>I believe it's possible to get an underline under the current line, rather than a highlight.</p>
  
  <p>This adds the highlight in my .vimrc:</p>
  
  <pre><code>set cursorline
  </code></pre>
  
  <p>This is what I've tried adding to get an underline:</p>
  
  <pre><code>:highlight CursorLine gui=underline cterm=underline
  </code></pre>
  
  <p>But it appears to make no difference.</p>
  
  <p>I'm using vim 7.4.629 on Centos 6.7 through putty, if that helps.</p>
