Argparse API change breaks argcomplete

[Matthias Lüscher]

Description: Ubuntu Noble Numbat (development branch)
Release: 24.04
python3-argcomplete: 3.1.4-1

Python argparse introduced an API change that breaks argcomplete. The upstream version of argcomplete got fixed here: https://github.com/kislyuk/argcomplete/commit/54a4846b3a774cd9037167898f3cce38ba9d58e8

I detected the issue using my python based tool edi. The issue can be reproduced as follows:

1. Install edi according to https://docs.get-edi.io/en/latest/getting_started.html#installing-edi-from-the-package-repository
2. Start to type "edi -v project" and hit tab for auto completion. The first level sub command will be proposed instead of the second level subcommand.
3. Patch /usr/lib/python3/dist-packages/argcomplete/packages/_argparse.py according to the above commit.
4. Start to type "edi -v project" and hit tab for auto completion. The correct second level commands such as "make" will be proposed.

It would be cool if the fix could get backported to Ubuntu 24.04 LTS too!
