Subject: [PATCH] don't use pagespec_match_list

This should be more efficient than pagespec_match_list since it short-circuits
after the first match is found.

The other problem with using pagespec_match_list here is it may throw an
error if a bad or failing pagespec somehow got into the dependencies.
