;;; Before the converter for scrollingPolicy was introduced (which wasn't
;;; even necessary), the one provided by Xm was called and people were using
;;; "AUTOMATIC" and "APPLICATION_DEFINED".  Everything was fine.
;;;
;;; After the converter was introduced, code was required to use 'automatic
;;; and 'application-defined instead.  Thus the change broke existing code.
;;;
;;; As a temporary solution, I'm now adding AUTOMATIC etc. to the list of
;;; legal values, but clearly some kind of concept is needed here...
