GETCONF allows zero arguments, contrary to spec
GETCONF takes at least one argument. Tor currently allows there to be zero arguments for
GETCONF. If there are zero arguments, it replies with
250 OK. A reply with a keyword and no
= can mean that a configuration variable has its default value. We've therefore committed to having no configuration variables named
OK. I suppose that's OK.
Probably the easiest thing to do is to document the existing behavior.
