Actually I find nothing wrong with having a helper function like this.
IIRC, show_file() was first, and then show_instance_file() came later.
There's some files that only exist for the top_instance, and I like the
fact that this is annotated that way.

I'm curious to know what the benefit of removing show_file() is?
