Now that I can agree with.   Getty has never been a friendly place.

I also think this belongs in Getty despite Warners concern that you
can not turn it off, as Getty alread does Termios stuff, which
you control via /etc/ttys, so there is a place to make a knob should
it be implemented in getty.

This is a specific issue to hardwired terminals, which is what
getty was written for.

It could also fixes the issues that I have pointed out in
https://reviews.freebsd.org/D10642 with col/row not being
reset between logins which yields the propose patch ineffective.
