title: URL from $routeChangeStart route params in angularjs routes
body: <p>How would it be possible to get the <code>URL</code> hash fragment from route params in <code>$routeChangeStart</code>. </p>
  
  <pre><code>$scope.$on('$routeChangeStart', function (event, next, current) {
    // trying to get the url hash fragment from &lt;next&gt; param here
    // e.g. to_url_function(next) -&gt; '/my_path/1'
  });
  </code></pre>
  
  <p>Receiving the <code>URL hash</code> fragment would be easy using <code>$locationChangeStart</code> but this is not an option for me.</p>
