Would you mean that it should release all the node including
ascendants? Hmm, I think we might just need to update its parent
so that it doesn't get affected, because the strfilter__delete()
doesn't know which user variable points the parent of the given node.
E.g. If we remove "b*" from "(a* | b*)", just update it as "(a* | !*)"

Yeah, anyway, I'll update it for fixing the misses you pointed.

Thanks!
