Besides known results, a number of new features are found. The slope $|d\\rho/d\\theta |$ of the normalized superfluid density $\\rho=\\lambda^2(0)/\\lambda^2(\\theta)$ at the transition $\\theta=T/T_c=1$ has a minimum near the value of the pair-breaking parameter separating gapped and gapless states. The low-$T$ exponentially flat part of $\\rho$ for the s-wave materials is suppressed by increasing pair breaking.
