  38 * SUMMARY: Testing regexp with many backreferences
  39 * See http://bugzilla.mozilla.org/show_bug.cgi?id=202564
  40 *
  41 * Note that in Section 1 below, we expect the 1st and 4th backreferences
  42 * to hold |undefined| instead of the empty strings one gets in Perl and IE6.
  43 * This is because per ECMA, regexp backreferences must hold |undefined|
  44 * if not used. See http://bugzilla.mozilla.org/show_bug.cgi?id=123437.
