IPython 5.3 terminal: enter should execute not insert line break

This is a regression from 5.2.2 to 5.3 when using the terminal interface: if the cursor is in the middle of a line and I press enter, a line break is inserted into the line. On 5.2.2, pressing enter had the same effect as if the cursor was at the end of the line i.e. it executes the line I’ve just entered.

To reproduce: type foo(2, 3) (without pressing enter), move the cursor to be on the 3, then press enter.

It’s extremely rare that one wants to break lines in an interactive session, but quite common to go back to a line from history, modify the contents, and then immediately want to execute it. Please bring back the old behaviour.

If reverting it completely is not possible, would it work to have Shift+Enter to execute (as in notebooks) when in the middle of a line?

Unfortunately terminals technical limitation prevent us to do that. You can use Esc followed by Enter though.

Is there any way to configure this behavior? I expect the command should be executed instantly as well…
