dcfef27 cli: Reject arguments to -getinfo (Wladimir J. van der Laan)
Pull request description:
Currently it's possible to accidentally type e.g. bitcoin-cli -getinfo getbalance and get an answer which can be confusing; the trailing arguments are just ignored. To avoid this, throw an error if the user provides arguments to `-getinfo`.
