## The second param of listsinceblock

From [issue 8752](https://github.com/bitcoin/bitcoin/issues/8752#issuecomment-247988691)

> The second parameter (target confirmation) is quite strange and should probably be better > documented in the RPC help of listsinceblock (check original comment: #199 (comment))

From the actual docs here is it is:

> target-confirmations:    (numeric, optional) The confirmations required, must be 1 or more

However, that's misleading at best. I've seen at least one project thinking that `target-confirmations` means "filter to only show transactions of n target-confirmations". It's a weird param but I'd document it as

> target-confirmations: (numeric, optional) Return the hash of the block that has target-confirmations of confirmations, for use in a further call to listsinceblock
## Transactions confirmations

Says:

> "confirmations": n,       (numeric) The number of confirmations for the transaction. Available for 'send' and 'receive' category of transactions.

It should also say when it's < 0, it means the transaction conflicted that many blocks ago
## bip125-replaceable

There's an undocumented field of transactions "bip125-replaceable" which I believe has three possibilities "yes" "no" and "unknown"  (under what circumstances it says unknown, should also be documented)

"1. \"bitcoinaddress\"  (string, required) The bitcoin address to be associated with an account.\n"
            "2. \"account\"         (string, required) The account to assign the address to.\n"
            "\nExamples:\n"

                GetAccountAddress(strOldAccount, true);
