I think that "--$o" looks really weird, but that's subjective, of course.

However, the idea popped up in an other thread[1] that we might want
something like 'git rev-parse --absolute-path --git-dir', which wouldn't
really work with '--$o'.

Even if we don't go that route, perhaps it would be better to list the
options to be tested including their doubledash prefix.
