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 repo
cd repo
touch foo
hg add foo
for i in 0 1 2 3 4 5 6 7 8 9 10 11; do
    echo "foo-$i" >> foo
    hg ci -m "foo-$i" -d "0 0"
done

for out in "%nof%N" "%%%H" "%b-%R" "%h" "%r"; do
    echo "# foo-$out.patch"
    hg export -v -o "foo-$out.patch" 2:tip
done

echo "# exporting 4 changesets to a file"
