From 13d6f8703bacfb8543c9d22c01db60e083650cad Mon Sep 17 00:00:00 2001
From: Baptiste Jonglez <baptiste--git@jonglez.org>
Date: Sun, 13 May 2012 14:09:21 +0200
Subject: Factorize boolean user prompting.

Introduce a new `status_ask_bool()` function, and use it where
applicable.

This greatly reduces code duplication, and will allow handling special
events (resize, user escape) much more uniformely.
