Actually, it doesn't bother calling send-break, but I've found the point
where it doesn't.

Maybe the following is OK --- in fact, possibly we don't need the
ERRFLAG_ERROR bit set, but I don't think it's doing any harm.

One advantage of using a different bit would be we could abort back to
the top of ZLE rather than out of ZLE and back in again, which would
mean you finally had the ability to embed push-line in other widgets.
But that's for another day.
