  * 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 -
