Is this correct? This means old code

		if (tp->t_line)
			(*linesw[tp->t_line].l_start)(tp);

is now changed to

		if (tp->t_linesw)
			(*tp->t_linesw->l_start)(tp);

but old tp->t_line was initialize to 0 in ttymalloc() and now
new tp->t_linesw is initialized to linesw[0], which is declared
in tty_conf.c. (i.e. it is not NULL.)

I'm not sure about the new line discipline scheme, but
shouldn't we check if tp->t_linesw is equal with linesw[0] or not?
