I dislike implicit ordering of arguments even less. Having -foo -bar behave
differently to -bar -foo is bad. We already have this a bit for things like
-net, but splitting something into two as a parsing hack seems really lame.

How about -drive args=whatever,unparsed_name=bah

Where unparsed_name is defined to be the last argument, and blah is
interpreted literally.
