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. thanks -- PMM
