Exit code in case of an error is always 1 since Python 3.13

Bug report

Bug description:

We noticed a failure of our Vim test suite on the Github Windows runners, when it was updated from python3.12 to python3.13.

Vim basically does run in a terminal exit(123) and expects the return code to be 123, however, since python3.13 the return code seems to be 1.

Note this works find on the linux jobs, just on Windows this does not work correctly. Also note, python3 -c 'exit(123)' seems to work correctly, only when using an interactive session it doesn't seem to work right.

I was able to reproduce this on Linux as well. Looking into it. (Note that this is specific to the REPL, this doesn't happen when running normal files.)

Thanks. For now I have been working around it in the Vim test suite.
