Re: make `occur' use word at point as default

[Richard M. Stallman]

    Why? There is currently a good deal of redundancy in the bindings for
    `next-history-element' and `previous-history-element'. These minibuffer
    history-list commands are bound to *FOUR PAIRS* of keys: (1) arrows [up] /
    [down], (2) C-n / C-p, (3) M-n / M-p, and (4) [next] / [prior]. (Well,
    actually, [prior] is then rebound to `switch-to-completions'.)

C-n and C-p do not run these commands; they do the usual cursor motion.
NEXT could conceivably be used to access another default.
But I think it would be more convenient to add it to the list for
C-p to access.
