I also like the idea, but is there already consensus on the starting
question: what to do with - I call it - stacked arguments?

$ mkdir -p d/d
$ echo foo > d/f
$ echo bar > d/d/g
$ ln d/f d/d/f
$ du -s d d/d

I omitted the result, but I think Paul's question
is the important one:
  "how much disk space I'll reclaim by removing ..."
Therefore, and from a user's perspective, I'd expect
du to count d/d again for the sum of the first argument d.

Is this covered by the proposal?
What would be the output for the above example?

Have a nice day,
