Sorry, my mistake.  Actually, I didn't  see gsl_odeiv2_evolve_apply,
but gsl_odeiv_evolve_apply.  Hope, this is a clear - the patch is
posted to GSL bugreport db & related to official, mainline code.

192: "if (final_step)" - step size isn't halved here (or near this line)

Step size is reduced only near line 210: "if (hadjust_status ==
GSL_ODEIV_HADJ_DEC)"
