Is it possible to retrieve from an overlay the parameters front-advance and rear-advance that was given to make-overlay?Without that it is not possible to make a new copy of an overlay AFAICS.The source code of `copy-overlay' answers this question.

Stefan PS: The comment says "easily" because you can of course insert+remove a char to check whether the position of the overlay's boundary stays "in front" or not.
