[TUHS] run commands at login in v6 and stty

[Brian Walden]

6th Edition used the Thompson shell as /bin/sh. I don't think it had
those capabilities. Sometimes you could find an early version of the
Bourne shell in /bin/nsh (new shell) in v6.

The 7th Edition made the Bourne shell /bin/sh. And there sometimes
you could find the Thompson shell in /bin/osh (old shell).
