Hi Bernt,

Thanks for the easy to follow-instructions.

I've been able to reproduce this error using Emacs23.  It looks as
though the `filter-buffer-substring-functions' variable is not defined
in any Emacs prior to 24.  I am not sure what the best way is to remove
all usage of the now-deprecated `buffer-substring-filters' variable
without using this new potentially-missing variable.

For now I've reverted this commit, while I try to figure out the best
solution here.

Thanks -- Eric
