Buffer marks are now internal to buffers so you do not have to worry
about their disposal. Unfortunately they are not retained in the file
when you save (any more than their owner, the buffer is).

The MCL team has been doing a fabulous job taking care of these details;
I have it on good authority that window-object is/will be documented in
the MCL 2.0 final Reference.

It worked fine for me. Thanks.
Note to others: in the example, #'test-drag-checker ensures that
only the word "average" is grabbable.
