A missing factor of $1/2$ in the previous leading-order result is identified. The next-to-leading order result has a compact form and is in good agreement with existing numerical calculations. The percentage error increases with $\\alpha$, from a few percent for $\\alpha\\sim 0.1$ to about $50\\%$ for $\\alpha\\sim 0.4$.
