It would be better if it weren't there. One way to obtain this would
be to use constants that, at a given level in an expression subtree,
were numbered the same, so you might have C1*(C2*x + C2*y) + C1*(C2/x
+ C2/y). So if the renumbering did that for testing purposes, the
doctests and tests would pass.
