Javascript syntax error when jQuery updated to 1.8+

I hope this helps anyone with the same problem.

After update jQuery to 1.8 via jQuery Update module, I've got this error

Uncaught Error: Syntax error, unrecognized expression: , .form-placeholder-exclude-children *, .form-placeholder-exclude

To solve this you have to open form_placeholder.js and change this:

      var include = Drupal.settings.form_placeholder.include;
      include += ', .form-placeholder-include-children *';
      include += ', .form-placeholder-include';

      var exclude = Drupal.settings.form_placeholder.exclude;
      exclude += ', .form-placeholder-exclude-children *';
      exclude += ', .form-placeholder-exclude';

To this:

      var include = Drupal.settings.form_placeholder.include;
      if(include){
        include += ', ';
      }      
      include += '.form-placeholder-include-children *';
      include += ', .form-placeholder-include';

      var exclude = Drupal.settings.form_placeholder.exclude;
      if(exclude){
        exclude += ', ';
      }
      exclude += '.form-placeholder-exclude-children *';
      exclude += ', .form-placeholder-exclude';
