[PATCHv3 0/6] --dirstat fixes, part 2

Hi,

Here's version 3 with patch 5/6 changed to use integer permille calculation instead of floating point percent calculations. Patch 6/6 also has minor updates caused by the 5/6 changes (s/percent/permille/ plus updated test vectors). The other patches are unchanged.

Have fun! :)
