Eric,

Well, it didn't work :(.  

However, I think I managed to fix it.  I think you have an ulterior
motive: to make me learn elisp properly once and for all... ;-).

Attached is the updated ob-maxima.el file with two changes:

1. quoted =identity= in the =mapconcat= sexp.
2. asked =split-string= to split on newlines so that (a) the regex for
   the rat line would match *and* (b) so that the output is faithful to
   what maxima generates.

I hope these make sense!  I've gone through the code and I think I
understand it.  More importantly, the output is now essentially the same
as I was getting before which makes me quite happy.

I'll do some more testing but the various tests I have tried should
cover most aspects that I ever use.

Thanks,
eric
