Hi Jos,

SWI-Prolog uses I/O wrappers if it is running in a Windows console to
support colored output and unbuffered input. This only used to check
output. I've now added test for input. This also makes
stream_property/2's tty(Bool) property work as it should.

Should be in tomorrows daily builds.

                 Cheers --- Jan
