The more I think about it, the less sure I become.  Pretty much every
CC-derived mode does (define-derived-mode my-mode prog-mode ...) anyway
and according to the macro expansion, its keymap's parent is set to
(current-local-map) which should be equivalent to `prog-mode-map'.
Could very well be a non-issue in practice and merely faulty testing by
the user...

I've assigned copyright already, but reckon this is a one-line patch.
Before I submit anything, I'd like to make sure it's needed and the
change works out as expected.
