(echo_now): Update before_command_echo_length.

(Freset_this_command_lengths): Reset this_command_key_count etc.
immediately rather than arranging to do it later.
(before_command_key_count_1, before_command_echo_length_1)
(before_command_restore_flag): Vars deleted.
(add_command_key): Don't handle before_command_restore_flag.
(read_char, record_menu_key): Don't update before_command_key_count or
before_command_echo_length.
(read_char): Don't handle before_command_restore_flag.

(command_loop_1): Don't call adjust_point_for_property
in direct-output clauses if it wouldn't be called in the ordinary case.
