That should work on everything later than V6. The MIT PWB1 tty handler (link in a prior message) not only supported a 'kill line' (we generally used '^U') which actually visibly deleted the old line contents (on screen terminals, of course; on printing terminals you're stuck), it also had suppport for '^R' (re-type line) and some other stuff.
