It seems that `forward-line', `forward-char', `forward-word'
and `backward-char' now takes 1 as the default, and it also
seems to be the case that using `backward-char' does no longer
make the byte-compiler say that the correct way is to use
(forward-char -1) - which is good, since `backward-char' is
more idiomatic - but (forward-char -1) still works, as do
(backward-char -1) - i.e., that's the same as (forward-char 1)
- or, now, (forward-char) ...

Take a look at `forward-button' tho, and `backward-button',
with those, N is still explicit ... don't know why, I suspect
a reason?
