I remember spending a while hunting out a PC terminal emulator that would
handle double-height properly; eventually I gave up. There was one (I think it
might have been Odyssey) which came fairly close, but all the others seemed to
make a total mess of it.
It's one of the things that's been nagging at me about some sort of "do
everything" terminal emulator, because I'm not sure whether supporting
double-height introduces all sorts of problems when otherwise trying to
support "classic" terminals.
