title: JSLint reports “Insecure '^'” on "^&;" from JavaScript: The Good Parts - ignore?
body: <p><a href="http://books.google.com/books?id=PXa2bby0oQ0C&amp;pg=PA41" rel="nofollow">JavaScript: The Good Parts p41</a> contains the following regex:</p>
  
  <pre><code>/&amp;([^&amp;;]+);/g
  </code></pre>
  
  <p>which is used to find all HTML entities such as <code>&amp;gt;</code>. If one validates this code with JSLint it reports</p>
  
  <blockquote>
    <p>Insecure '^'</p>
  </blockquote>
  
  <p>While this is correct strictly speaking, I still believe it's fine to ignore it. Or not?</p>
