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.
