Undocumented Xenix screen escape sequence

I found that Xenix (2.3.1) responds to the DEC "private" escape sequences
ESC [ ? 7 h turn wraparound on
ESC [ ? 7 l turn wraparound off
I.e., if you send or type ESC [ ? 7 l the screen no longer wraps to the
next line when you get to the right hand side of the screen (the cursor
sticks there until you carriage return).
This only affects the current multiscreen, other screens remain in the mode
they were in.
ESC [ ? 7 h puts you back into wraparound mode.
(I happened on this quite by accident. I think I had telnet'd to a VAX
and told it I was a VT100 and at some point it sent the wrap off sequence.)
This is not documented in screen(HW). It is documented in my old DEC VT100
manual. It's no big deal, it was just rather confusing for a couple of days.
