* 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.
