cf. <http://article.gmane.org/gmane.emacs.diffs/135579>

To try the old `widget-keymap' definition to reproduce the bug,
I needed to eval the following form, that exists in gnus-art.el,
after reverting the `widget-keymap' definition:

(set-keymap-parent gnus-article-mode-map widget-keymap)

With this, I learned that `set-keymap-parent' uses a copy of
a parent keymap, i.e., a change made in a parent keymap has no
effect on *this* keymap.
