PAL has not used clang-format at all, my contributions have been an effort to
support the PAL formatting style so we can start to use the tool.

I was not aware of `DisableFormat`, it's not as intuitive as having everything
in the ignore file but it can be a compromise if you're completely opposed to
adding the `**` change.

Like you said, this is not ideal as it relies on anyone adding/moving files
that may need to be ignored to regenerate the clang-format-ignore file.
`**` could handle these cases without a need for manual intervention.

Are you seeing a gap in the unit tests I have? I think I have these cases
covered but can add more specific unit tests if you have an example.
