+* 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...
