This is parsing multiple arguments.
If you want it space-separated, you can do that, just as a single
argument. Otherwise, what you're doing is taking multiple arguments
and joining them. I'm not sure what you expect to see, but your
examples here pretty clearly show that you are taking multiple
arguments, and joining them with spaces.
