Glob ordering is used in a variety of places, including figuring out conf.d and really needs to be stable. Other ordering, like completions, is really just cosmetic and can change if it makes for a nicer experience. So we uncouple it by copying the wcsfilecmp from 3.0.2, which will return the ordering to what it was in that release. Fixes #6593
