Hi Robert, yes it does help.  The behavior is as expected when I simply 
add that bit to my maxima-init.lisp file.  Curious as that appears to be 
same code as is in the mactex-utilities file, so I wonder where it breaks.

With regard to the indices... I guess I should have mentioned I use a 
maxima-init.mac to texput the output as I want it.  It is an upstream 
conflict, where I have defined \newcommand{\alphaathreethree}{...} etc.  
In latex it seems commands cannot have numeric characters so I had to 
spell them out.

Thanks a bunch!
