Or to rephrase, qemu acts as though it uses GNU getopt_long_only() (some
programs like gcc do likewise), but MOST programs that take long opts
behave like they use getopt_long().  It is only the getopt_long_only()
variant that accepts long options with a single dash, when it is
unambiguous with POSIX getopt() parsing of multiple smashed-together
short options.

[well, qemu rolls its own option parser instead of using
getopt_long_only(), but you get the picture]
