I think the change looks good.  I've just realized that the other caller
of button--properties might need a tweak.

In unbuttonize-region, we should change this call:
(remove-text-properties start end
                            (button--properties nil nil nil))

to:
(remove-text-properties start end
                            ;; t to ensure help-echo gets reset.
                            (button--properties nil nil t))

But, now we don't know if the help-echo property was effectively added
by the library or it was already there :-(.  Sadness.
