    * io/io.h (struct st_parameter_dt): Assign expanded_read flag to
    unused bit. Define new variable line_buffer_pos.
    * io/list_read.c (free_saved, next_char, l_push_char,
    read_logical, read_real): Replace use of item_count with
    line_buffer_pos for line_buffer look ahead.
    (read_logical, read_integer, parse_real, read_real, check_type):
    Adjust location of free_line to after generating error messages
    to retain the correct item count for the message.
