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

hg init a
cd a
hg init b
echo x > b/x

echo '# should print nothing'
hg add b
hg st

echo '# should fail'
hg st b/x
hg add b/x

echo '# should fail'
hg add b b/x
hg st

echo '# should arguably print nothing'
hg st b

echo a > a
hg ci -Ama a

echo '# should fail'
hg mv a b
hg st
