/*
* String . match ( regexp )
*
* If regexp is not an object of type RegExp , it is replaced with result
* of the expression new RegExp ( regexp ) . Let string denote the result of
* converting the this value to a string . If regexp . global is false ,
* return the result obtained by invoking RegExp . prototype . exec ( see
* section 15 . 7 . 5 . 3 ) on regexp with string as parameter .
*
* Otherwise , set the regexp . lastIndex property to 0 and invoke
* RegExp . prototype . exec repeatedly until there is no match . If there is a
* match with an empty string ( in other words , if the value of
* regexp . lastIndex is left unchanged ) increment regexp . lastIndex by 1 .
* The value returned is an array with the properties 0 through n - 1
* corresponding to the first element of the result of each matching
* invocation of RegExp . prototype . exec .
*
* Note that the match function is intentionally generic ; it does not
* require that its this value be a string object . Therefore , it can be
* transferred to other kinds of objects for use as a method .
*
* This file tests cases in which regexp . global is false . Therefore ,
* results should behave as regexp . exec with string passed as a parameter .
