+    This code was extracted from Mailman.Generator.Generator, version 2.1.4:

+    Most other Generator will be created not setting the foldheader flag,
+    as we do not overwrite clone(). The original clone() does not
+    set foldheaders.
+
+    So you need to set foldheaders if you want the toplevel to fold headers
