Output claims the configuration came from project root (filesystem root) when in reality it was user-level config.

Describe the bug

The verbose would claim that the filesystem root was identified as the project root (this is correct) and the configuration file came from /pyproject.toml (this is false).

To Reproduce

• Create a test file in a directory where is no pyproject.toml present (up the filesystem root)
• Format it with Black with --verbose
• Create a user level config file and configure line length to be something very small
• Reformat using the same command and observe the wrong output

❯ black test.py --check -v
Identified `/` as project root containing a file system root.
Sources to be formatted: "home/ichard26/programming/oss/test.py"
test.py already well formatted, good job.

All done! ✨ 🍰 ✨
1 file would be left unchanged.

❯ echo "[tool.black]
  line-length = 10" > ~/.config/black

❯ black test.py --check -v
Identified `/` as project root containing a file system root.
Sources to be formatted: "home/ichard26/programming/oss/test.py"
Using configuration from project root.
would reformat test.py

Oh no! 💥 💔 💥
1 file would be reformatted.

Expected behavior

That the output would report either it came from user level configuration or at least not claim it was project configuration 'cause it's not.

Environment

• Black's version: 22.1.0 and d038a24
• OS and Python version: CPython 3.8.5 under Ubuntu 20.04.03 LTS

Additional context

This made it very confusing to debug an unrelated test suite issue :)
