[mesa-users] Mass transfer lag in binary

While running the binary_donor_only test suite under version 5596,
unmodified except for stopping_age = 1d10, it appears that there is a lag
in the mass loss. Examination of the binary_history.data
columns lg_mstar_dot_1 and lg_mstar_dot_2 shows that lg_mstar_dot_1 lags by
one step, consistently.

I have seen the same problem in binary_donor_only_implicit_mdot and for
various binary parameters as well. I'm guessing that this might be a bug?
