title: Change window.location prototype to disable certain redirects?
body: <p>I'm trying to selectively disable <code>window.location</code>, using Greasemonkey, at the start of the document.</p>
  
  <p>I don't want to fully disable javascript, just disable some redirects done with javascript.  They look like this:</p>
  
  <pre><code>window.location = "unwanted url";
  </code></pre>
