I cannot reproduce this in Emacs 23.1.  Please show a complete recipe,
starting with "emacs -Q", to reproduce this problem.

One possibility is that you see this in a file that turns a major mode
which uses mode-require-final-newline to set the buffer-local value of
require-final-newline.  In that case, you may wish to customize
mode-require-final-newline, or maybe reset require-final-newline in a
mode hook.
