This IMNSHO cleans up the object hashing. The hash expansion is separated out into a function of its own, the hash array (and size) names are made more obvious, and the code is generally made to look a bit more like the object-ref hashing. It also gets rid of "find_object()" returning an index (or negative position if no object is found), since that is made redundant by the simplified object rehashing. The basic operation is now "lookup_object()" which just returns the object itself. There's an almost unmeasurable speed increase, but more importantly, I think the end result is more readable.
