i prepared an answer to the other branch of the thread, but i noticed
that i first have to learn, before i answer.

That exactly is the point which i do not understand. How does FLOW3 know
that "*.jpg" belongs to "subject"?
Is that any default routing?
What happens when i have two different arguments which both could have
files as value?

With your below examples it would be --foo *.jpg --bar *.png
or --foo one.jpg --foo2 two.jpg --bar one.png --bar2 two.png
But what would it be with your above example?
...-G -- *.jpg *.png
?
