This STDOUT vs _log() choice is a bit irregular, and I think you might
be better off abandoning it completely. Richard, Alex, do we really
need to optionally route printfery to log or stderr? (considering _log
is NOW stderr by default now, and -D option gives you some flexibility
there). Can we have just log and drop STDOUT mode?

Peter
