Interactive Window code entry cell should not have an execution count

[IanMatthewHuff]

Execution count happens when something actually executes. The code input section should not have an execution count before it actually executes:

Spyder works this way. It shows what the new execution count would be.

Although personally I'd rather just have the >>> instead of the count. Count seems weird to me too.

Yeah, I'd seen Spyder do that. My opinion count = execution seems better. Not a big deal if we want to look more Spyder like, but I'd prefer looking like Jupyter.

In our case the execution is always sequential, so it probably isn't a big deal. It definitely matters in the case of Jupyter Notebooks, as cell executions can be out of order.
