From 1278ebdbc3167883f32095491990fbdc7cdf8b5e Mon Sep 17 00:00:00 2001 From: Dirk Gouders Date: Sun, 19 May 2013 21:49:34 +0200 Subject: [PATCH] mconf/nconf: mark empty menus/menuconfigs different from non-empty ones Submenus are sometimes empty and it would be nice if there is something that notifies us that we should not expect any content _before_ we enter a submenu. A new function menu_is_empty() was introduced and empty menus and menuconfigs are now marked by "----" as opposed to non-empty ones that are marked by "--->". This scheme was suggested by "Yann E. MORIN" . Signed-off-by: Dirk Gouders Tested-by: "Yann E. MORIN" Reviewed-by: "Yann E. MORIN" Signed-off-by: "Yann E.
