Thanks for calling me *profoundly *astute. :) If the developer wants to add more items to ignore, they can be safely added within the square brackets.
My advice assumed that the file would be broken into separate lines, and each item checked individually. Also note, that as *Cereberus *did, by using the ^ symbol in front (and outside the square brackets), that means beginning of item, and is not used as a negation.
