You probably want to specify --count-links if you want hardlinked files
(like your example k and l) to be considered by du as separate files:

    $ echo foo > k
    $ ln k l


    $ du -c k l
    4       k
    4       total

    $ du -c --count-links k l
    4       k
    4       l
    8       total
