I don't remember the specific case that motivated the change.
IIRC I changed it mostly because the limitation was arbitrary (as you
can see in the patch, which doesn't actually change the code).
I didn't know that CL had decided to give a completely different meaning
to the unary / than the natural generalization of the behavior of (/ X1
X2 ... Xn). It seems backward to me, so I guess my sense of aesthetics
would incite me to simply revert my patch, adding a comment that for the
semantics of the unary / there is a conflict between the natural choice
and CL compatibility.
