  The supersymmetry technique [A. V. Kolesnikov and K. B. Efetov, Phys. Rev.
Lett. 83, 3689 (1999)] predicts a two-scale behavior of wavefunction decay in
disordered wires in the crossover regime from preserved to broken time-reversal
symmetry. We have tested this prediction by a transmission approach, relying on
the Borland conjecture that relates the decay length of the transmittance to
the decay length of the wavefunctions. Our numerical simulations show no
indication of two-scale behavior.
