I would argue that counting the number webs available for gathering, in particular when restricted to some burrow, is a perfectly valid use case for item. Thus, I would much prefer an option along the lines of -ignore-webs . (Yes, I actually think that the default should be to include them.)

Addendum: In fact, the more common use case is probably to forbid all items inside some cavern burrow or outside some burrow that designates the "safe area" of the fort. So yes, item definitely should include webs by default.

that's fair; will change
