Every initial commit have no parent, thus if you try to fetch full log, you'll receive error like this:
git diff '--numstat' 'f5baa11a1c82dc42ade5c291e9f061c13b66bc2f' '' 2>&1:fatal: ambiguous argument ''To fix this we can use
git showcommand if current object have no parent. This command can accept all options fromgit diff, the only difference is that we should not pass (empty) parent commit hash.
