+ * Date: 22 June 2001
+ *
+ * SUMMARY:  Regression test for Bugzilla bug 87231:
+ * "Regular expression /(A)?(A.*)/ picks 'A' twice"
+ *
+ * See http://bugzilla.mozilla.org/show_bug.cgi?id=87231
+ * Key case:
+ *
+ *            pattern = /^(A)?(A.*)$/;
+ *            string = 'A';
+ *            expectedmatch = Array('A', '', 'A');
+ *
+ *
+ * We expect the 1st subexpression (A)? NOT to consume the single 'A'.
+ * Recall that "?" means "match 0 or 1 times". Here, it should NOT do
+ * greedy matching: it should match 0 times instead of 1. This allows
+ * the 2nd subexpression to make the only match it can: the single 'A'.
+ * Such "altruism" is the only way there can be a successful global match...
