The "Changes" section should have been after the '---' mark, below, to
avoid it being in the commit log.

It works very well, and really mimicks the behavior we have in nconf! :-)

(But see a very minor comment below.)

That's not well centered (sorry, I initially missed it), this should
have been '28':
( nb_buttons * button_size + (nb_buttons - 1) * button_separation ) / 2
(      5     *      8      + (     5     - 1) *        4          ) / 2 = 28

But that's just eye-candy, and only is only obvious on very small terminals.

Regards,
Yann E. MORIN.
