  *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 object obj1 will not include a

  * flag. The flags parameter for obj2 will be undefined in the sense

  * of not being provided.
