// The following was originally for the Rich Text Editor ggedit.js (= "green grass editor", because it uses mootools.js). 
// Then ggedit and mootools proved to be much too flakey, so we replaced it with jquery.FCKEditor. But it doesn't really 
// hurt anything to leave the following in and let developers do something extra on clear (if they use this script).
