We show that, except for the correction in the longitudinal superfluid density rho/sub s/X = rho(1-(3/2)(hv/sub F//delta)= Vertical Bar(lxdel)lVertical Bar), all the nonanalytic contributions to the supercurrent which have been studied previously vanish. It is shown that, if one does not use a gauge transformation, one has to go beyond the linear approximation for the spatial variations of the gap in order to treat consistently the superfluid velocity.
