If there's an inclusion list and an exclusion list, there's only a need
to delete things from the exclusion list if the exclusion list has bad
initial values, and never any need to delete things from the inclusion
list. And since reliably rewriting links in HTML when compressing is at
best tricky and at worst impossible (think JavaScript navigationy
things), is there ever going to be any need for removing from the
exclusion list?
