Hi dear @motea927 thanks for this PR and sorry it took long to be reviewed.

I have made some refactors on copy implementation to make it simpler and also merged the functionality with the (more universal) ignore option introduced in #1430 and added tests.

Merging with new option comes with slight inconsistency that ignore patterns should "not" be prefix with public/. I think we can fix it later since is a minor requirement.
