Re: mark_object and hash tables fail to mark all objects?

[Richard Stallman]

    When changing mark_object() for Lisp_Process, it occured to me that
    maybe hash tables should be handled the same way as struct window,
    because right now it explicitly marks its members, thereby missing to
    mark count, key_and_value, next_free, next_weak.

I added comments to explain why the code is correct.
