`Local in buffer *Summary gmane.emacs.gnus.user*' means that the
variable was `nil' in a global context, and it was somehow set when you
entered that buffer.

That's funny.  I am not sure why this is happening.  With an Emacs 23.X
installation here, I can start Emacs without any sort of init file by
typing in my shell prompt

    emacs -q --no-site-file --no-splash .bashrc

Then split the window in two side-by-side windows by typing `C-x 3' and
I see the long lines wrapped.  Now I'm a bit confused.
