Actually, the default is even easier ... if no matching line in
/etc/whatever_the_file_is_called is found, login proceeds. No need to
call an external program that always exits with a status of 0.
BTW, for this "to continue or not continue" to work, the interface to
tty_relatives() needs to change ... i.e. it needs to return an int, 0 for
"continue" and non-zero (-1 probably) for "don't continue".
