-0500  A belated followup to Maarten's lengthy post on this:  I
notice that, unlike -mfx-, the new -margins- command does not
even report marginal effects for interaction terms, e.g.  sysuse
auto logit foreign price mpg c.mpg#c.price, nolog margins,
dydx(*)  This makes sense to me: the interaction term can't
change unless one of its component terms changes. So, the
marginal effects for price and mpg incorporate the effect caused
by the interaction term.  So, does this mean that marginal
effects of interaction terms are no longer an issue because
Stata is now handling them correctly, blending in the
interaction effects with the main effects? Or, would people
still want to (somehow) compute a marginal effect for the
interaction term?  I used continuous variables in the ab
