	There is a simple fix to prevent the tty driver from erasing
past the begining of the line. In file 'tty.c', change in the routine
in_char()		[around line 3610 in the book]

	chuck(tp);
	echo(tp,'\b');
	echo(tp,' ');
	echo(tp,'\b');
	return;

to

	if (chuck(tp) != -1) {
		echo(tp,'\b');
		echo(tp,' ');
		echo(tp,'\b');
	}
	return;

	In this way, it won't erase if 'chuck' says it shouldn't.
