title: Displaying the relative path of the currently edited file in Vim's statusline?
body: <p><code>:help statusline</code> claims <code>%f</code> will render as:</p>
  
  <blockquote>
    <p>Path to the file in the buffer, as typed or relative to current directory.</p>
  </blockquote>
  
  <p>When I <code>set statusline=%f</code>, the path in the statusline is sometimes relative, but often absolute.</p>
  
  <p>Is there a way to make sure the path displayed is always relative?</p>
