OK, fair enough. Though it does seem to be having _some_ 
quasi-global effect, in that it influences what the cairo terminal 
prints in reponse to "show term"...

It's not really a matter of preference: I'm thinking of, for 
example, printing the name of a variable which includes one or more 
underscores in a key, title or label of some sort. It's just broken 
if that turns into a subscript.
