Hi Daniel and Greg,

I believe I have fixed these issues.  I am not entirely sure though if  
I do understand Bastien's code well enough.  Please test and report  
back.

One addition I have made:  If the sub/superscript is a single char, it  
it typeset in the normal math italic.  If it is longer, it is typeset  
in roman.  If someone needs an explanation for this convention, ask,  
and I will explain.

- Carsten
