No, no, no! (It's getting hard, let me rephrase)

/dev/tty is mode 666 root/wheel
/dev/tty[pqrs]* are mode 600 root/wheel, and are changed to mode 620
`whoami`/tty when you log in.

Proposed permission change is:
/dev/tty stays mode 666 root/wheel. We donc change /dev/tty
/dev/tty[pqrs]* turns into mode 620 root/tty. They are still changed to
mode 620 `whoami`/tty when you log in.
