How on Earth did you spot that?  :-)

Yes, it's true, that variable doesn't exist.  I've found the commit
where it came into the doc string (from 2003-11-21), and the variable
itself was not in that commit.  I can only assume that Martin (my
predecessor on CC Mode) created it as part of the patch, documented it,
then before committing the change decided it wasn't needed, but forgot
to amend the documentation.  Or something like that.

I'll fix the documentation in the next day or so.

Thanks!
