I don't understand.  If my .emacs is

(custom-set-variables
  ;; custom-set-variables was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.
 '(whitespace-check-indent-whitespace nil))

and I launch Emacs without arguments, activate `whitespace-global-mode',
and open some file, sequences of eight spaces at bol do not get
highlighted.  Maybe someone else can check this.

 '(indent-tabs-mode nil))

and I launch Emacs without arguments, activate `whitespace-global-mode',
and open some file, sequences of eight spaces at bol do not get
highlighted.  Again I ask others to check this.

I changed `whitespace-indent-regexp' in November 2006 from

(concat "^\\(\t*\\)    " "    ")

to

"^\t*\\(        \\)+"

so maybe that's a reason.
