function content_multigroup_node_form_fix_parents in Content Construction Kit (CCK) 6.3

Fix form element parents for all fields in multigroups.

The $element['#parents'] array needs to reflect the position of the fields in the $form_state['values'] array so that form_set_value() can be safely used by field validation handlers.
