coreutils stty settings documented but invalid

[Brian Inglis]

Trying to keep my profile/s (aliases, functions) consistent across systems,
wondering why some stty settings, supported on Linux systems, although
documented on Cygwin (info stty SETTING), are treated as invalid e.g. cmspar,
xcase, echoprt, extproc, and not just ignored like other settings:

	$ stty cmspar xcase echoprt extproc
	stty: invalid argument ‘cmspar’
	Try 'stty --help' for more information.

The output from stty -g varies never/little on Cygwin, and is much shorter than
any Linux output. The docs do not state whether these settings are meant to be
portable or not.

Current stable distro stty/coreutils versions vary from Cygwin 8.26, SuSE 8.29,
Debian/Ubuntu 8.30, to Fedora 8.31.
