Re: [babel] (wrong-type-argument number-or-marker-p nil)

Hi Eric,

Thanks for looking at this so quickly.

Patching from email is a skill still on my horizon.  I tried several  
times without success and without gaining any idea how to resolve the  
problem(s).  You might not want to wait for me to figure out how to  
patch.  It took longer than I'm willing to admit on this list for me  
to get to the point where I could make an emacs backtrace and longer  
still to understand git sufficiently to make sense out of git bisect.   
git am looks very mysterious to me right now.

All the best,
Tom
