disk IGNORE rule in DEFAULT section

Maybe I'm just a little sleep deprived, but I thought that if a machine had a disk slice that didn't have an explicit DISK <blah> line defined for it, it would use the rule as defined in the DEFAULT section. However, I have a bunch of machines that apparently are _not_ using the rule as defined in the DEFAULT section. Below is a copy of the relevant parts of the DEFAULT section (at the very bottom of the hobbit-clients.cfg file)

DEFAULT <other non-related DISK IGNORE rules> DISK %^/archive[0-9]* IGNORE DISK * 90 95

I know technically the "DISK *" should probably be "DISK .*", but I thought that's how it was by default. Am I just wrong with my PCRE?
