Thanks for the investigation. It seems that pdb imports rlcompleter
since python 3.13 and ipython always imports pdb at startup.

Thank you. I think the fix is good.

BTW, python 3.13 introduces pyrepl and leads to the warning "can't use
pyrepl: terminal doesn't have the required clear capability;
TERM=dumb".

Maybe we should set PYTHON_BASIC_REPL=1 to suppress the warning when
starting the inferior python process?
