I meant s/lead/lean/, of course.

As usual, I'm utterly confused by the $(pwd) versus $PWD thing. So let
me review what I did to see if it makes sense. :)

I copied this bit from t1515, which sets up a similar scenario. I think
it _probably_ works either way because of the environment-variable
conversion magic that Windows bash does.

I'm not sure if it matters here. I almost wrote $TRASH_DIRECTORY, but
that I think is in the same form as $PWD. Either would be fine.
