title: jQuery selector with single quote concatenation
body: <p>Im using jquery min 1.3.2. Could you help me to fix jQuery selector? It doesn't work with single quote user name. If user = "Peter", everything works OK.</p>
  
  <pre><code>var user = "Pet'e";
  var id = "1";
  
  var value = $("a[name=" + user + "][id=" + id + "]").attr("todo");
  </code></pre>
