🐛 Bug report

cannot append list args to default_config_files

To reproduce

from jsonargparse import CLI

def test_fn(
    nums: list[int] = [0],
    strs: list[str] = ["a"],
):
    pass

if __name__ == "__main__":
    CLI(test_fn, default_config_files=["config.yaml"])

nums:
- 1
strs:
- x

$ python test.py --nums+ 2 --print_config
nums:
- 2
strs:
- x

Expected behavior

python test.py --nums+ 2 --print_config got

nums:
- 1
- 2
strs:
- x

Environment

• jsonargparse version: 4.13.2
• Python version: 3.9.12
• How jsonargparse was installed: pip install jsonargparse
• OS: Linux

This has been fixed in commit 363e05d and included in v4.13.3 just released.

Dear @mauvilsa, I found this issue still happened with subcommand:
Here is a example:

from jsonargparse import CLI

def test_fn(
    nums: list[int] = [0],
    strs: list[str] = ["a"],
):
    pass

def empty_fn(
):
    pass

if __name__ == "__main__":
    CLI([test_fn, empty_fn], default_config_files=["config.yaml"])

test_fn:
  nums:
  - 1
  strs:
  - x

λ python test.py test_fn --nums+ 2 --print_config
nums:
- 2
strs:
- x

I pushed a fix for the subcommands in commit 03fed89.

Thanks, @mauvilsa! It works now.
