   * SUMMARY: Testing Error.prototype.toString()
   *
   * Revised: 25 Nov 2002
   * See http://bugzilla.mozilla.org/show_bug.cgi?id=181909
   *
   * Note that ECMA-262 3rd Edition Final, Section 15.11.4.4 states that
   * Error.prototype.toString() returns an implementation-dependent string.
   * Therefore any testcase on this property is somewhat arbitrary.
   *
   * However, d-russo@ti.com pointed out that Rhino was returning this:
   *
   *               js> err = new Error()
   *               undefined: undefined
   *
   *               js> err = new Error("msg")
   *               undefined: msg
   *
   *
   * We expect Rhino to return what SpiderMonkey currently does:
   *
   *               js> err = new Error()
   *               Error
   *
   *               js> err = new Error("msg")
   *               Error: msg
   *
   *
   * i.e. we expect err.toString() === err.name if err.message is not defined;
   * otherwise, we expect err.toString() === err.name + ': ' + err.message.
   *
   * See also ECMA 15.11.4.2, 15.11.4.3
