Subject: [PATCH] Curses: prevent menu search without menu options

First noticed this when watching someone livestream, and managed
to figure it out from there: The window that pops up when looking
at a pile of objects under you by pressing ':' is marked as a menu,
but has no selectable options.  Curses still allowed you to use the
menu-search command (':') on it.

Prevent the menu search command in windows with no selectable entries.
