[Qemu-devel] [PATCH 01/10] cocoa: do not create a spurious window for -version

["Andreas Färber" <andreas.faerber@web.de>]

From: Tristan Gingold <gingold@adacore.com>

When invoked with -version, qemu will exit just after displaying the version,
so there is no need to create a window.
Also handles --XXX options.
