^$ matched twice #66

This finds three matches of ^$, but there are only two:

var
  f: TFLRE;
  matches: TFLREMultiStrings;
  captures: TFLREMultiCaptures;
  i: Integer;
begin
  f := TFLRE.Create('^$', [rfMULTILINE]);
  f.ExtractAll(LineEnding+'abcd'+LineEnding+LineEnding+'defg',matches) ;
  f.MatchAll(LineEnding+'abcd'+LineEnding+LineEnding+'defg',captures) ;
  writeln(length(matches), ' = ', length(captures));
  for i := 0 to high(captures) do
    writeln(captures[i][0].Start, ' ', captures[i][0].Length);
