Drat. It's either "-display sdl,window_close=off" or
"-display gtk,window-close=off" (note the underscore vs. minus between 
"window" and "close"). Please disregard this patch, that "underscore vs. 
minus" problem should get fixed first, so we can point the users to the 
parameter with the right syntax. I'll try to come up with some patches...
