Thanks.
I had a look into src/du.c and adding such an --inodes option
was pretty easy, see attached patch.

Comments?

P.S. I must admit that the (unusual) corner case of listing the
inodes usage of the working directory when it is deleted is not Zero:

  $ d=$(pwd)/d ; mkdir $d; cd $d; rmdir $d
  $  stat -c "%h %n" .
  0 .
  $ du --ino .
  1     .

Have a nice day,
