extern void Menu_MakeIndirected(menu_ptr menu, int entry, char *buffer, int size)
/*
* Makes the specified menu item 'indirected text', pointing to 'buffer'.
* ie the menu item will contain the text held in 'buffer'.
*
* Similar to 'Menu_MakeWritable()' except this doesn't produce a writable
* entry. It does provide a user defined buffer though, and updating
* this is simpler (and quicker) than calling 'Menu_SetText()'.
* The validation string is set to null, as this is only really of use
* with a writable icon, when the user may need to restrict the characters
* entered.
