The logic in this code obviously predates the multiple monitor
capability of qemu and looks increasingly silly these days.

I think the intention of this piece of code is to get a reasonable
default for the -nographic case: have monitor and serial line muxed
on stdio.

With the new default_serial and default_monitor variables we have now
doing just that became much easier ;)
