* 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  -
