* 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...
