I already did "M-x rgrep" on emacs.git/lisp directory before posting
anything about the function.

    (define-key MAP [remap next-line] 'new-next-line)

is great, though.

I dreamed that Emacs had such abstraction that user could redefine
global keyboard bindings and it would be nice and usable throughout the
system. In particular I was interested in only one user: me. But never
mind, it was naïve and I no longer have that dream. I realized that,
even though redefining individual keys is simple, some of the default
bindings still exist conceptually everywhere in different major modes.
I'm not that motivated to redesign modes too because that's what it
takes to maintain consistency. Heavy keyboard customization just isn't
practically possible.

So, I'll just continue to use the default keys with the knowledge that,
although they are not the most ergonomic and fast for text editing, at
least they are quite consistent throughout the Emacs system, even the
GNU system.

Now let's move on. What's the next purely academic discussion we should
have here on emacs-devel? :-)
