Use a clang-format file that isn't at the root of the repo

[Ryanf55]

          > For clang-format, with a `.clang-format` file in the base of your repo:

  - repo: https://github.com/pocc/pre-commit-hooks
    rev: v1.3.5
    hooks:
      - id: clang-format
        args: [-i, --style=file]

Thanks for your reply. I will try it.

Clang-format has a limitation that it only looks in the current director, or above it, when searching for a config file.

I have multiple repositories, A, B, and C.
A and B have source code.
C has common configuration including the clang-format file, which is shared with B and C.

Latest clang-format has support for this: https://stackoverflow.com/a/70859277/11032285

Is there anything that I should do to use that?
