        * cus-edit.el (custom-filter-face-spec, custom-pre-filter-face-spec) 
        (custom-post-filter-face-spec): New functions.
        (custom-face-set, custom-face-value-create): Filter the face spec
        before and after customization.

It might have been cleaner to implement this with the
':value-to-internal' and ':value-to-external' widget attributes, which
exists for the purpose.
