So ... why did you put this patch in "Waiting on Author" state? AFAIK,
we had dropped the idea of relying on \sf for this, mainly because
Peter complained about \df+ no longer providing source code. I follow
his point: if you're used to using \df+ to see source code, you probably
can figure it out quickly if that command shows the source in a different
place than before. But if it doesn't show it at all, using \sf instead
might not occur to you right away.
