1. You can always set:

        let python_no_number_highlight = 1

   to prevent number highlighting and prevent the issues with your
   files.

2. Ken, thanks for researching this.

   Python syntax highlighting is in a strange situation right now.
   I am the author of the latest version used since the version 7.3.
   However, Neil still remained the maintainer.
   There was recently a post by Dmitry who wants to become
   the maintainer, but his code is based on Vim 6.1 instead of 7.3.

   So even my recent patch for my code is still not committed
   because it’s not clear obviously who gives the green light for
   these changes.

   That’s probably the reason why your change is not committed yet.

I’ll take a look at Ken’s patch and whether it changes the highlighting of 
anything else (it looks OK). Then we just need to figure out who wants to be an 
official maintainer of Vim Python syntax highlighting to get such changes in 
faster.

I do not mind doing it myself if Neil and other’s agree.

Thanks!

        Zvezdan
