title: why does _.escape modify / characters in Underscore.js?
body: <p>I was looking through the <a href="http://underscorejs.org/#escape" rel="nofollow noreferrer">Underscore.js api</a> and I noticed that <code>_.escape</code> escapes <code>&amp;</code>, <code>&lt;</code>, <code>&gt;</code>, <code>"</code>, <code>'</code>, and <code>/</code> characters. What surprised me was escaping <code>/</code>.</p>
  
  <p>Is there a reason to escape <code>/</code> characters that I don't know about?</p>
