[sorry for the HTML in the first try] Hi, I'm a longtime user of scipy and greatly appreciate your work. I'd like to ask/suggest something about minimize_scalar. It seems to me that the tol parameter is relative tolerance when the method is 'brent' and absolute tolerance when the method is 'bounded'. Isn't this confusing? Perhaps this parameter should be deprecated, until both methods can support either relative or absolute tolerance? Meanwhile, parameters with names such as 'abs_xtol' and 'rel_xtol' can be introduced, and invalid combinations of parameters and method would be rejected with a ValueError? Cheers.
