So I still think that we should not be including any new
-display subargument which mirrors the behaviour of -nographic.

-display represents an opportunity to provide a set of orthogonal
command line options which affect the handling of particular
devices; it ought to mean "what happens to VGA/video output?",
and should not change the behaviour of any other devices.

-nographic is effectively a convenience shortcut which changes
the behaviour of several different devices (display, serial,
parallel, at least). It doesn't belong under '-display' from
an orthogonality argument, and people who want it because it
is a shortcut will be better served by the existing '-nographic'
because it's less typing than '-display serial' anyway.

(Ideally we should document '-nographic' by saying that it
is equivalent to some set of other options including
-display none -serial stdio and whatever else it does.)
