teor 0cfeea2ecb Use a different symbol for each v5 Sapling field cardinality rule. 
Currently, the spec uses the double dagger symbol for both:
* present if and only if `nSpendsSapling + nOutputsSapling > 0`;
* present if and only if `nSpendsSapling > 0`.

To avoid confusion, use dagger for the first rule, and double dagger for the second rule.
