Bug report

Bug description:

The code in pymain_repl() in "Modules/main.c" needs to check _Py_GetEnv(config->use_environment, "PYTHON_BASIC_REPL"). Otherwise running with -i, or with PYTHONINSPECT set in the environment, ends up running the new REPL instead of the basic REPL after the command or script finishes.

CPython versions tested on:

CPython main branch

Operating systems tested on:

Linux
