function select_or_other_checkbox_value in Select (or other) 6.2

Helper function to determine the value for a checkbox form element.

Drupal core cannot discern the difference between an unchecked checkbox and a checked checkbox that has a value of '0'. This value callback will return NULL instead of an integer 0 for checkboxes that are not checked.
