Possible to add to script to parse all lists for stray "www."?

Awesome project, been using for a year now. As I've added and removed lists there are a few stray "www." entries that make it through from time to time. Is it possible to add a step in the middle of gathering the entries from various lists to remove the www. from them?

FWIW I'm using some local files as well formatted with http://example.com/lists/2dogs1bowl.txt type files that are downloaded from the internet with curl as domain lists.

Why do you want to remove www entries? They are different than the entries without www.
