Subject: Some line numbers missing when both whitespace and linum mode are enabled at the same time

Easy to reproduce:

1. Open any file with blank lines.
2. Enable linum-mode (line numbers displayed correctly)
3. Enable whitespace-mode (some line numbers, especially after a blank
line are missing)

I've checked this on never emacs versions and it's not working
correctly on any of them.
