// that the 0-th entry should be blank (and won't be displayed). (This is
// because we use a pulldown list, for which Cocoa uses the 0-th item as "title"
// in the button. This might change if we ever switch to a pop-up. Our direct
// use of the given NSMenu object means that the one can set and use NSMenu's
// delegate as usual.)
