17 * String.match( regexp )
18 *
19 * If regexp is not an object of type RegExp, it is replaced with result
20 * of the expression new RegExp(regexp). Let string denote the result of
21 * converting the this value to a string. If regexp.global is false,
22 * return the result obtained by invoking RegExp.prototype.exec (see
23 * section 15.7.5.3) on regexp with string as parameter.
24 *
25 * Otherwise, set the regexp.lastIndex property to 0 and invoke
26 * RegExp.prototype.exec repeatedly until there is no match. If there is a
27 * match with an empty string (in other words, if the value of
28 * regexp.lastIndex is left unchanged) increment regexp.lastIndex by 1.
29 * The value returned is an array with the properties 0 through n-1
30 * corresponding to the first element of the result of each matching
31 * invocation of RegExp.prototype.exec.
32 *
33 * Note that the match function is intentionally generic; it does not
34 * require that its this value be a string object. Therefore, it can be
35 * transferred to other kinds of objects for use as a method.
36 *
37 * This file tests cases in which regexp.global is false. Therefore,
38 * results should behave as regexp.exec with string passed as a parameter.
