diffstat: print 0 instead of nothing for 0 adds or removes

This is in line with how the stock diffstat behaves when processing a
single diff with no line modifications (like a binary diff).

#!/bin/sh

mkdir t
cd t
hg init
echo a > a
hg add a
hg commit -m test -d "1000000 0"
rm .hg/requires
hg tip
echo indoor-pool > .hg/requires
hg tip

true
