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

Hi,

I finally found the time to re-roll the remaining dirstat fixes,
incorporating feedback from Linus and Junio in the surrounding thread.

The first patch adds a number of testcases for --dirstat, guarding
against regressions.

The second patch fixes a small issue I found while playing around with
--dirstat=0.

The next three patches revamps the dirstat-related command-line options
and introduces a diff.dirstat config variable for controlling the
--dirstat defaults. The third patch here (accepting floating-point
percentage input) has some remaining questions mentioned in that email.

Finally, the last patch is a re-roll of the previous "RFC/PATCH 5/3"
that introduces a new dirstat mode, based on the diffstat analysis.


Have fun! :)

...Johan
