+       * printcmd.c (examine_i_type): New static - type for instructions.
+       (do_examine): For "i" format, specify examine_i_type.
+       (do_examine): Call value_at_lazy instead of value_at so that

+       (x_command): If examine data was not fetched, set convenience
+       variable "__" to void.
+       (_initialize_printcmd): Initialize examine_i_type.
