I noticed that behaviour, too, which differs from the manpage. Because
of that, I had added . /etc/profile to .bashrc in the first place.
Since bash is unchanged from the debian default in Knoppix, I can only
suspect that either the manpage is wrong, or the bash package maintainer
(dpkg -s bash) has changed bash's behaviour with a (probably, haven't
looked thoroughly) undocumented patch.
