python implementation of diffstat

Implemented as two functions: diffstat, which yields lines of text,
formatted as a usual diffstat output, and diffstatdata, which is called
inside diffstat to do real performing and yield file names with
appropriate data (numbers of added and removed lines).

#!/bin/sh

hg init
echo a > a
hg ci -Am0

touch .hg/store/journal

echo foo > a
hg ci -Am0

hg recover
