Thanks for the report.
global-whitespace-newline-mode basically does this:

(let ((whitespace-style '(newline-mark newline)))
  (global-whitespace-mode 1))

So it does the right thing in existing buffers, but not in future
buffers that are created later (because whitespace-style is back to its
default value).

I don't know why global-whitespace-newline-mode even needs to exist.
It would be simpler to remove it and just say "customize
whitespace-style to whatever you want, and call global-whitespace-mode".
