docs: The inverse of `_.escape`; this method converts the HTML entities
  `&amp;`, `&lt;`, `&gt;`, `&quot;`, and `&#39;` in `string` to their
  corresponding characters.
  
  Note: No other HTML entities are unescaped. To unescape additional HTML
  entities use a third-party library like [_he_](http://mths.be/he).
