I use both.  I readily concede that people familiar with QEMU probably
use single dash a lot more than double dash.  I don't think we should
get rid of single dash, unless we decide to bite the bullet and clean up
our command line without regard for backward compatibility, as Thomas
proposed elsewhere in this thread, and others proposed before, multiple
times.

I don't entertain the idea of compatibility breaks lightly.  But our
command line is genuinely nasty.  The closer you look, the nastier.
