Just for clarity, a correct simulation wouldn't abort a non-halting
program either, would it?  Or have I misunderstood this correctness?

A non-halting program cannot be simulated correctly in a finite time.
So, it depends whether we can call it a correct simulation, when it does
not abort. But, for some meaning of 'correct', indeed, a simulator
should not abort a non-halting program either.

 That is not what I said.

What you said logically entails that a correct simulation
of 1 step counts as a correct simulation of 0 steps.

What I said is that if a program needs two steps for a simulation, it is incorrect to simulate only one step and then abort and report it will never halt.
English seems to be a difficult language for you.

I am talking about the correct simulation of N steps and you
are trying to get away with saying there is no such thing
as the correct simulation of N steps. That is either terribly
confused or dishonest, yet incorrect either way.
