Previously: * If only ["" => "x"] was present, the original string was returned without warning. * If both ["" => "x"] and at least one more element was present, false was returned without warning. New behavior: * Ignore "" keys in the replacement array (and perform any remaining replacement). * Throw a warning indicating that an empty string replacement has been ignored. Closes GH-4792.
