Daira Hopwood 58add67726 * Specify that diversifier indices for Orchard should be chosen uniquely, not randomly. 
* Vanity diversifiers are not an issue for Orchard given that it does not have its own
  payment address format, and given the use of "jumbling" (ZIP 316) in unified addresses.
  Remove the corresponding note from \crossref{orchardkeycomponents}.

ZIP-244: Clarify sapling shared anchor hashing (#490) 
* ZIP-244: Clarify sapling shared anchor hashing

Unlike the orchard shared anchor, the sapling v5 transaction shared anchor
is hashed into *each* spend.

* Uppercase Sapling and Spend

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.
