Tom's changes made to GDB are IMO the perfect examples of what we don't want:

-      /* ... fall through for unsigned ints ...  */
+      /* fall through */

-                /* For other instructions, fallthru.  */
+                /* fallthru.  */

-      /* fall thru to manual case */
+      /* fall thru */


So, because of its excessive pickiness, the warning ends up making the user 
butcher informative comments.  How is that helpful?
