bug in recentf.el

[Heiko Gerdau]

Hi,

this seems to be a bug showing up in the recentf.el package:

How to reproduce: if you customize the recentf menu to be toplevel 
(recentf-menu-path nil) and visit a file using that menu, than the 
toplevel recentf menu gets to equal submenus containing both the recentf 
menu.

if you use the default settings ( submenu of the file menu) the effect 
described above does not happen.

I see this on Linux with the current stable 21.3 and the current cvs 
version of gnu emacs (21.3.50.1).

Greetings
Heiko
