This breaks existing command line setups -- if I say
"-display none" I just mean "don't do a display", not
"please also give me a monitor". We already have a
"do what I mean" option for "no graphics", which is
"-nographic". The advantage of -display none is that
it does only and exactly what it says it does.

Setups using semihosting for output now get a spurious
load of output from the monitor on their terminal.

I think we should revert this; I'll send a patch.
