Ah, right, and indeed the code is just parsing off space-separated arguments one at a time. It's unfortunate that this is done so much differently from \sf. One could imagine, perhaps, checking for parentheses in the arguments and parsing differently depending on whether they're there. But that's getting into the realm of a new definition rather than a bug fix. regards, tom lane
