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