The culprit appears to be a missing case statement in ttyrub(); we've
been running with this fix:

*** tty.c~	Thu Jun  5 03:09:35 1986
--- tty.c	Wed Jun 15 10:39:29 1988
***************
*** 1506,1511 ****
--- 1506,1512 ----
  		case BACKSPACE:
  		case CONTROL:
  		case RETURN:
+ 		case NEWLINE:
  			if (tp->t_flags&CTLECH)
  				ttyrubo(tp, 2);
  			break;
