You don't need this change, just set your $InputValues as an array:

  $InputValues['color'] = array('red', 'green');

Actually, assuming that a comma is a separator will mean that a comma can  
never be part of the value. For example, you wouldn't be able to have  
checkboxes like "Austin, TX", "Los Angeles, CA" and "Paris, France".

Also, as admins are already using the current implementation, the change you  
suggested will break their wikis when they upgrade. We normally try to not  
do this when we can.
