Subject: [PATCH] Export all variables from the initial context when creating a
submenu
When a submenu is created, only the exported variables are copied to the
new menu context. But we want the variables to be global, so export lets
export all variables to the new created submenu.
Also, don't unset the default variable when a new submenu is created.
