bash 4.1.1 fails to login in restricted mode

[Isaac Salsberg]

When invoked as rbash login shell in MAC OS X 10.4.11, it  fails to 
execute in restricted mode, allowing cd and the use of / as leading command.

This is the installed version:
GNU bash, version 4.1.0(1)-release (powerpc-apple-darwin8.11.0)
Copyright (C) 2009 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later 
<http://gnu.org/licenses/gpl.html>

If I just execute rbash after login, then it enables the restricted 
mode, which does not make much sense.

This is the very same bug that was reported long ago with GNU bash, 
version 2.05b.0(1)-release (powerpc-apple-darwin8.0)
