REPL takes extra key presses on long inputs that wrap around lines

Bug report

Bug description:

The new REPL has an issue when outputting at the right edge of the console window. It tries to output a "" at the end, and then print the typed character at the beginning of the next line. This works fine on the first line. The 2nd line the "" + char doesn't show up until after you press a 2nd char. And at the 3rd line it takes 3 chars, and so on.

CPython versions tested on:

CPython main branch

Operating systems tested on:
