For shrinking images, you're supposed to use a negative size. However, the leading minus makes getopt think that it's an option and so you get the help text if you don't use -- like in 'qemu-img resize test.img -- -1G'. This patch handles the size first and removes it from the argument list so that getopt won't even try to interpret it and you don't need -- any more. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
