You could redefine the default values in glm.control, eg to use 10^-7 in
the convergence test

glm.control<-function (epsilon = 1e-07, maxit = 10, trace = FALSE)
{
    if (!is.numeric(epsilon) || epsilon <= 0)
        stop("value of epsilon must be > 0")
    if (!is.numeric(maxit) || maxit <= 0)
        stop("maximum number of iterations must be > 0")
    list(epsilon = epsilon, maxit = maxit, trace = trace)
}
