Unbind of namespaced 'change' event unbinds all 'change' events (IE only)

Description

For example, myInput.unbind('change.myNS') will also unbind events bound using myInput.bind('change', function), myInput.change(function) or myInput.bind('change.otherNS', function).

Seems to be confined to Internet Explorer (present in v6-8).

      $(function(){
        $('#myform input').bind('change', function(){alert('change event');});
        $('#myform input').bind('change.ns', function(){alert('change event');});
        $('#myform input').change(function(){alert('change 2 event');});
        $('#myform input').unbind('change.otherns');//will unbind all three events above
      });
    </script>

Just to add, even doing a namespace-wide unbind with no event type specified (ie unbind('.namespace')) seems to cause this problem.

I've just had a look at the source, and this seems to be caused a function in jQuery.event.special.change (and similarly in jQuery.event.special.submit) being incorrectly named "remove" rather than "teardown", causing all of the special functionality to be removed when any single event is removed.

Does someone want to update this, or direct me to some instructions on how I'd go about doing that?
