 * 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.
 * See http://bugzilla.mozilla.org/show_bug.cgi?id=223273 and its testcase.
