  * Date:    11 Nov 2002
  * SUMMARY: JS shouldn't crash on extraneous args to str.match(), etc.
  * See http://bugzilla.mozilla.org/show_bug.cgi?id=179524
  *
  * Note that when testing str.replace(), we have to be careful if the first
  * argument provided to str.replace() is not a regexp object. ECMA-262 says
  * it is NOT converted to one, unlike the case for str.match(), str.search().
  *
  * See http://bugzilla.mozilla.org/show_bug.cgi?id=83293#c21. This means
  * we have to be careful how we test meta-characters in the first argument
  * to str.replace(), if that argument is a string -
