Here is some working code.  Prolog gurus: I'm a mere user so if 
you're going to flame it, flame it in a nice way, as Dame Edna
would say...

    read_line(L):-
   	get_chars([],L).

   get_chars(IN,OUT):-
	get0(C),
	get_rest(C,IN,OUT).

   get_rest(10,L,L):-
	!.
   get_rest(C,IN,[C|OUT]):-
	get_chars(IN,OUT).
