michael@0:  * SUMMARY: Passing (RegExp object, flag) to RegExp() function.
michael@0:  * This test arose from Bugzilla bug 61266. The ECMA3 section is:      
michael@0:  *
michael@0:  * 15.10.3 The RegExp Constructor Called as a Function
michael@0:  *
michael@0:  *   15.10.3.1 RegExp(pattern, flags)
michael@0:  *
michael@0:  *   If pattern is an object R whose [[Class]] property is "RegExp"
michael@0:  *   and flags is undefined, then return R unchanged.  Otherwise 
michael@0:  *   call the RegExp constructor (section 15.10.4.1),  passing it the
michael@0:  *   pattern and flags arguments and return  the object constructed
michael@0:  *   by that constructor.
michael@0:  *
michael@0:  *
michael@0:  * The current test will check the first scenario outlined above:
michael@0:  *
michael@0:  *   "pattern" is itself a RegExp object R
michael@0:  *   "flags" is undefined
michael@0:  *
michael@0:  * The flags parameter will be undefined in the sense of not being
michael@0:  * provided. We check that RegExp(R) returns R  -
