Explanation of total of Hashtbl.hash_param is not right. #6869
Original bug ID: 6869
hashtbl.mli says about Hashtbl.hash_param:
Hashing performs a breadth-first, left-to-right traversal
The value of [total] is actually capped to HASH_QUEUE_SIZE=256 in byterun/hash.c therefore specifying larger than 256 is equivalent with 256. This should be noted in the comment.
