Description
Hello. I wrote something to make back references(\0-\9) work with re.sub. Not the prettiest but it does seem to work. Unfortunately, I did not understand how to commit this properly. So I'm leaving it here for now. Sorry for the inconvenience.

Research direction
Start by reviewing re.py and the existing re.sub implementation to understand how replacement strings are parsed. Check the issue's proposed back-reference behavior for \0-\9, then identify the relevant existing test coverage. Done means re.sub supports the requested back references without breaking current replacement behavior.
