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.
