the way the wyse and televideo terminals work is that the magic cookie
is a marker. if you wipe out the marker, you lose the attribute.
one way this really shows up is if you have a begin reverse marker on line
3 and an end marker on line 7. now scroll the screen 3 lines, and all of a
sudden, the 4 lines which were in reverse video return to normal video.
ugly.
