whitespace_test.txt which can be used to reproduce problem.

Description of problem:
The whitespace-mode in emacs seems broken in emacs 23.3.1. The mode is supposed to highlight trailing whitespace and other whitespace issues, but no highlighting happens in recent emacs releases.


Version-Release number of selected component (if applicable):
23.3.1

How reproducible:
100 %

Steps to Reproduce:
1. Run "emacs -q whitespace_test.txt". whitespace-test.txt is attached to this bug.
2. Evaluate the lisp code in the file (M-x eval-buffer)
3. Whitespace in the file should be highlighted.
  
Actual results:
No whitespace highlighting happens.

Expected results:
