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