 *
 * SUMMARY: Passing (RegExp object, flag) to RegExp() function.
 * This test arose from Bugzilla bug 61266. The ECMA3 section is:      
 *
 * 15.10.3 The RegExp Constructor Called as a Function
 *
 *   15.10.3.1 RegExp(pattern, flags)
 *
 *   If pattern is an object R whose [[Class]] property is "RegExp"
 *   and flags is undefined, then return R unchanged.  Otherwise 
 *   call the RegExp constructor (section 15.10.4.1),  passing it the
 *   pattern and flags arguments and return  the object constructed
 *   by that constructor.
 *
 *
 * The current test will check the first scenario outlined above:
 *
 *   "pattern" is itself a RegExp object R
 *   "flags" is undefined
 *
 * The flags parameter will be undefined in the sense of not being
 * provided. We check that RegExp(R) returns R  -
