+ * Creation Date:   30 May 2001
+ * Correction Date: 14 Aug 2001
+ *
+ * SUMMARY:  Regression test for bugs 83293, 103351
+ * See http://bugzilla.mozilla.org/show_bug.cgi?id=83293
+ *     http://bugzilla.mozilla.org/show_bug.cgi?id=103351
+ *     http://bugzilla.mozilla.org/show_bug.cgi?id=92942
+ *
+ *
+ * ********************   CORRECTION !!!  *****************************
+ *
+ * When I originally wrote this test, I thought this was true:
+ * str.replace(strA, strB) == str.replace(new RegExp(strA),strB).
+ * See ECMA-262 Final Draft, 15.5.4.11 String.prototype.replace
+ *
+ * However, in http://bugzilla.mozilla.org/show_bug.cgi?id=83293
+ * Jim Ley points out the ECMA-262 Final Edition changed on this.
+ * String.prototype.replace (searchValue, replaceValue), if provided
+ * a searchValue that is not a RegExp, is NO LONGER to replace it with
+ *
+ *                  new RegExp(searchValue)
+ * but rather:
+ *                  String(searchValue)
+ *
+ * This puts the replace() method at variance with search() and match(),
+ * which continue to follow the RegExp conversion of the Final Draft.
+ * It also makes most of this testcase, as originally written, invalid.

+  * This example is from jim@jibbering.com (see Bugzilla bug 92942)
+  * It is a variation on the example below.
+  *
+  * Namely, we are using the regexp /$/ instead of the regexp //.
+  * The regexp /$/ means we should match the "empty string" at the
+  * end-boundary of the word, instead of the one at the beginning.

+  * Note: 'Zabc' is the result we expect for 'abc'.replace('', 'Z').
+  *
+  * The string '' is supposed to be equivalent to new RegExp('') = //.
+  * The regexp // means we should match the "empty string" conceived of
+  * at the beginning boundary of the word, before the first character.
