Sounds great. I'll have a go at this.

Thanks Guillem, I'll use your branch as a basis then.

I agree that options now are more suitable than a separate filter.d/

My gut feeling is that a path is ran through all filters in order, and
the last one has the final word. I. e. the most special filter should
--exclude /usr/share/doc/* --include /usr/share/doc/*/copyright
This would filter everything except "copyright". In this pathological
--exclude /usr/share/doc/* --include /usr/share/doc/*
nothing would be filtered at all. Did you discuss something else back
