Description (last modified by jakesson)

This is a part of #3944.

Brent does currently not detect if the residual corresponding to the initial guess (or previously converged solution) is below the tolerance, before going into the bracketing step. As a consequence, Brent takes one or two bracketing steps to bracket the root and then a couple of convergence steps to find the solution.

A check to detect the case when the residual corresponding the initial guess should be added, in which case the algorithm returns successfully.
