Ultrix 3.1 "stty raw; stty -raw" changes things

[Chris Siebenmann]

 On Ultrix 3.1, a "stty raw" also changes nl to -nl; this means that
"stty raw; stty -raw" leaves your tty scrambled (I know that people
don't use stty raw very often, but we have a local application that
uses stty instead of fondling the tty modes in C for portability).
Ultrix 2.2 behaved properly, and the stty manpage makes no mention of
the change.
