michael@0:  *SUMMARY: Passing a RegExp object to a RegExp() constructor.
michael@0:  *This test arose from Bugzilla bug 61266. The ECMA3 section is:      
michael@0:  *
michael@0:  *  15.10.4.1 new RegExp(pattern, flags)
michael@0:  *
michael@0:  *  If pattern is an object R whose [[Class]] property is "RegExp" and
michael@0:  *  flags is undefined, then let P be the pattern used to construct R
michael@0:  *  and let F be the flags used to construct R. If pattern is an object R
michael@0:  *  whose [[Class]] property is "RegExp" and flags is not undefined,
michael@0:  *  then throw a TypeError exception. Otherwise, let P be the empty string 
michael@0:  *  if pattern is undefined and ToString(pattern) otherwise, and let F be
michael@0:  *  the empty string if flags is undefined and ToString(flags) otherwise.
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:  * We check that a new RegExp object obj2 defined from these parameters
michael@0:  * is morally the same as the original RegExp object obj1. Of course, they
michael@0:  * can't be equal as objects - so we check their enumerable properties...
michael@0:  *
michael@0:  * In this test, the initial RegExp obj1 will include a flag. The flags
michael@0:  * parameter for obj2  will be undefined in the sense of not being provided.
