2.2 (hah) and 3.0. I would try it on 4.0 but my -current box is asleep.

>Description:

This trivial patch adds support for mark and space parity.

I have no idea what standard this is based on as it was purely to get
mark and space parity to work under Tcl. Basically you turn PAREXT and
PARODD to get mark and PAREXT for space.

I'm not sure if extra magic is needed for reading back the flags or not,
but I guess that the tty layer caches that info for the application.


>How-To-Repeat:

Patch for 3.0 is at http://www.gsoft.com.au/~doconnor/PAREXT-3-patch

I should be trivial to apply to current.
