Dear all,

When I made this change I *attempted* to achieve backwards 
compatibility with other packages such as mathspec that relied on this 
information, but I didn't quite get it right.

I'll post an update in a couple of days to correct this problem and to 
give a little time for any additional problems to be unearthed. Please 
let me know if you see anything else amiss.

Sorry for any inconvenience,
Will
