patch: take messages out of the function so that extensions can add entries Extensions will want to have interactive thing for more operations or particulary want to show more verbs. So this patch takes out the message thing from the function so that extensions can add verbs to this. The curses one is also not in any function so extensions can add more actions and verbs there.
