(Pieter Wuille)0fa2f88added includedWatchonly argument to listreceivedbyaddress/...account (JaSK)f87ba3dadded includeWatchonly argument to 'gettransaction' because it affects balance calculation (JaSK)a5c6c5dfixed tiny glitch and improved readability like laanwj suggested (JaSK)d7d5d23Added argument to listtransactions and listsinceblock to include watchonly addresses (JaSK)952877eShowing 'involvesWatchonly' property for transactions returned by 'listtransactions' and 'listsinceblock'. It is only appended when the transaction involves a watchonly address. (JaSK)83f3543Added argument to listaccounts to include watchonly addresses (JaSK)d4640d7Added argument to getbalance to include watchonly addresses and fixed errors in balance calculation.
