+ * In any case:
+ * - keys that have a group width <= the old width are okay (because
+ * they could not possibly have been associated with the old type)
+ * If the key type increased in size:
+ * - keys that already have a group width >= to the new width are okay
+ * + keys that have a group width >= the old width but < the new width
+ * might have to be enlarged.
+ * If the key type decreased in size:
+ * - keys that have a group width > the old width don't have to be
+ * resized (because they must have some other wider type associated
+ * with some group).
+ * + keys that have a group width == the old width might have to be
+ * shrunk.
+ * The possibilities marked with '+' require us to examine the key types
