All pairwise contrasts of equal-weight marginal means for ONE factor.
The joint covariance of the fitted means is retained in SE(diff), not replaced
with MSE(1/n_i+1/n_j). Numeric covariates default to complete-case means.
at fixes covariates or other factor levels and permits simple-effect comparisons.
