  23 * SUMMARY: Passing (RegExp object, flag) to RegExp() function.
  24 * This test arose from Bugzilla bug 61266. The ECMA3 section is:
  25 *
  26 * 15.10.3 The RegExp Constructor Called as a Function
  27 *
  28 *   15.10.3.1 RegExp(pattern, flags)
  29 *
  30 *   If pattern is an object R whose [[Class]] property is "RegExp"
  31 *   and flags is undefined, then return R unchanged.  Otherwise
  32 *   call the RegExp constructor (section 15.10.4.1),  passing it the
  33 *   pattern and flags arguments and return  the object constructed
  34 *   by that constructor.
  35 *
  36 *
  37 * The current test will check the first scenario outlined above:
  38 *
  39 *   "pattern" is itself a RegExp object R
  40 *   "flags" is undefined
  41 *
  42 * This test is identical to test 15.10.3.1-1.js, except here we do:
  43 *
  44 *                     RegExp(R, undefined);
  45 *
  46 * instead of:
  47 *
  48 *                     RegExp(R);
  49 *
  50 *
  51 * We check that RegExp(R, undefined) returns R  -
