The attached patch causes the Newton and Steffenson one-dimensional root finders to initialize using GSL_FN_FDF_EVAL_F_DF rather than GSL_FN_FDF_EVAL_F and GSL_FN_FDF_EVAL_DF. This should result in faster initialization for problems where the function and derivative are expensive to evaluate and involve redundant calculations.
