Ah!  I see what I was doing wrong.  I thought mistakenly that the add method
modified opts in situ, so I was not assigning its returned value to opts...

So this is what I have now (CE below is my own bit of syntactic sugar):


      var opts = $( 'option', select );
      var cur_length = opts.length;

      // add options to select element if necessary
      if ( new_length > cur_length ) {

        // array of newly created option elements
        var os = $.map( new Array( new_length - cur_length ),
                        function () { return CE( 'option' ) } );

        opts = opts.add( $( os ).appendTo( select ) );
      }

Boy, I like this!  (The dummy array in the map is a bit of a waste,
though...)

Anyway...  thank you!
