title: How to highlight rulerformat
body: <p>I want <strong>hi</strong>ghlight the <strong>rulerformat</strong> in my <code>.vimrc</code>.</p>
  
  <p>I have</p>
  
  <pre><code>set ruler
  set rulerformat=%55(%{strftime('%a\ %b\ %e\ %I:%M\ %p')}\ %5l,%-6(%c%V%)\ %P%)
  </code></pre>
  
  <p>I have subsequently tried all of the following:</p>
  
  <pre><code>hi rulerformat ctermbg=1
  hi rulerformat ctermbg=red
  hi Group1 ctermbg=red "if you modify the rulerformat slightly you can try to access group 1
  </code></pre>
  
  <p>I don't necessarily want it to be red, but I thought that would stand out the most; anyway, I just cannot get it to work, and I didn't really find anything online (a somewhat unintensive search yielded nothing much). So, how does one <strong>hi</strong>ghlight the <strong>rulerformat</strong>?</p>
