Alan Riley privately and kindly pointed to what I suspect
is the correct explanation. 

-tokenize- does by default parse on spaces, but 
it also allows options, so it is looking for them. 
It can thus, understandably, get confused by unprotected commas. 

It follows that I need to fix -makematrix- to 
ensure that this doesn't happen.
