title: GitHub Pages trailing slashes
body: <p>Using Middleman on GitHub Pages with <a href="https://middlemanapp.com/advanced/pretty_urls/" rel="noreferrer">directory_indexes</a> enabled, I wonder if I can somehow get rid of the trailing slash GitHub adds.</p>
  
  <p>My urls are basically: <code>/foo-bar -&gt; /foo-bar/index.html</code>.</p>
  
  <p>Visiting <code>/foo-bar</code> on GitHub Pages redirects to <code>/foo-bar/</code>.</p>
  
  <p>Is there any way to prevent this redirect?</p>
