michael@0:  * SUMMARY: Testing regexps with unescaped braces
michael@0:  * See http://bugzilla.mozilla.org/show_bug.cgi?id=228087
michael@0:  *
michael@0:  * Note: unbalanced, unescaped braces are not permitted by ECMA-262 Ed.3,
michael@0:  * but we decided to follow Perl and IE and allow this for compatibility.

michael@0:  * See http://bugzilla.mozilla.org/show_bug.cgi?id=188206 and its testcase.
