bug#7810: 24.0.50; global-whitespace-newline-mode impossible to turn off

[Deniz Dogan]

I start Emacs with the -Q switch.

M-x global-whitespace-newline-mode RET
(Global-Whitespace-Newline mode enabled)

Then I want to turn it off:
M-x global-whitespace-newline-mode RET
(Global-Whitespace-Newline mode enabled)

As you can see, it is still enabled. The mode line shows "Fundamental
NL WS". It is possible to turn off global-whitespace-mode but
global-whitespace-newline-mode is still in effect. I tried to execute
(global-whitespace-newline-mode nil) and
(global-whitespace-newline-mode 0) as well, but neither of them turn
the mode off.

I think it is impossible to turn off global-whitespace-newline-mode.
