title: Disable "use the function form of use strict" but keep the "Missing 'use strict' statement" warning
body: <p>I am using jslint to validate my code.<br>
  I have "use strict" on all my pages.<br>
  How can I disable the message "use the function form of 'use strict'" but keep the "Missing 'use strict' statement" warning, so I won't forget to put it on new files?</p>
  
  <p>Thanks</p>
