Well, the set_fact is supposed to only register or select anything where
the size parameter of the files attributes is 0. The ones that are
printing just [] don't fit that criteria, and therefore, shouldn't be
included in the debug output. Yet they are, so that's what I'm trying to
fix/clean up first.
Thanks,
Harry
