* SUMMARY: Testing regexps with unescaped braces
* See http://bugzilla.mozilla.org/show_bug.cgi?id=228087
*
* Note: unbalanced, unescaped braces are not permitted by ECMA-262 Ed.3,
* but we decided to follow Perl and IE and allow this for compatibility.
*
* See http://bugzilla.mozilla.org/show_bug.cgi?id=188206 and its testcase.
