No. If you type C-n twice fast enough, Emacs will behave the same as if you type C-2 C-n. > And C-u 1001 C-n followed by C-u 1000 C-p also moves point by 1 line, > just like C-n does, yet I hope you would not expect it to behave exactly > the same WRT scroll-conservatively. If you type these two commands quickly so that there's no intervening redisplay, Emacs _will_ behave the same, and I would expect it to. And I don't see any point in continue arguing about this, since we have very different expectations and different perspective. Let's agree to disagree.
