	* remote-vx.c (net_step): Delete step-range code.
	* remote.c (remote_resume, init_all_packet_configs)
	(set_remote_protocol_E_packet_cmd)
	(show_remote_protocol_E_packet_cmd)
	(remote_protocol_E, show_remote_cmd, _initialize_remote)
	(remote_protocol_e, set_remote_protocol_e_packet_cmd)
	(show_remote_protocol_e_packet_cmd): Ditto.
