So? Consistency would be better, but that horse left before the barn
was even built. It is called filename "globbing" because even the
wild inconsistency between regular expression implementations
doesn't quite encompass most file globbing rules.
I'll grant that better documentation would be nice. But at this point,
matching the platform expectation (at the cost of some additional
cross-platform inconsistency) may be the lesser of evils.
And frankly, for many use cases the windows algorithm is better.
It only hurts when it brings up something you weren't expecting *and*
you didn't double-check before performing a dangerous operation.
I can assure that I've found unexpected file matches under unix
semantics as well.
