Data::Dumper: Comment on previous optimization

The optimization in the previous commit to Data::Dumper (sparse seen
hash) is not complete: It is so far only applied to non-RV SVs. This
also means that it's safe not to check for weak-refs. Applying the
optimization to RVs should be possible, but is not as easy (I think).
