Summary:                    du does not print identical directory name multiple
times (mismatch with coreutils)
Description: 
Coreutils behavior:

$ mkdir A
$ du A
4       A
$ du A A
4       A
4       A
$ du A A A
4       A
4       A
4       A


Busybox behavior:

$ mkdir A
$ ./busybox du A
4       A
$ ./busybox du A A
4       A
$ ./busybox du A A A
4       A

Busybox doesn't duplicate the directory entries.  Perhaps this is a
feature and coreutils is actually behaving incorrectly?

Note that when A is a REGULAR FILE (rather than a directory), coreutils
and busybox behave identically and duplicate the entries:

$ touch A
$ ./busybox du A
0       A
$ ./busybox du A A
0       A
0       A
$ ./busybox du A A A
0       A
0       A
0       A
