The linefeed that is printed after each stage (if anything is) is separate from the actual output string of the stage (that is, this linefeed is not passed on as input to the next stage). That means there is no way to suppress that linefeed in Retina currently, because even an empty result will print this linefeed. There should be an option for all stages which suppresses this (i.e. changes the semantics from Console.WriteLine to Console.Write).
