From b2c92b2eb4ba8695923b72ff05493068b2be5934 Mon Sep 17 00:00:00 2001 From: Baptiste Jonglez Date: Mon, 14 May 2012 12:38:20 +0200 Subject: src/utils.c: Add a status_ask_simplechoice() function We need a simpler version, based on the previously defined `status_ask_choice()` function, that asks to choose amongst a number of alternatives that can simply enumerated, without needing to bind keys on them.
