Pull request description:
These paths can be hit for probably a number of reasons, and ISMINE spendability is not a requirement to call it. For example: During watch-only transaction creation, previous transaction in wallet, pubkey imported, but not the witnessscript associated with the prevout. In this case I think no/minimal comment is better than specific and soon to be out of date.
