+#   For regular files, for each bit set in the octal number
+#   corresponding to the set-user-ID-on-execution or the
+#   set-group-ID-on-execution, bits shown in the following table shall

+#   or not requests to set or clear the set-user-ID-on-execution or
+#   set-group-ID-on-execution bits are honored.
