I am not sure how WinBoard behaves if the engine is Pondering in a Human vs. engine game. With engine vs. engine, it has to choose between the engines, and only prints the output of the one that has the move. But the Human causes no output even if he has the move, so there really is no need to suppress the engine ponder output.
The official mechganism for this is to use the 'telluser' command. You then get a popup box with the text. If the same engine gives a new 'telluser', the old box disappears, and a new one appears.
