Re: [PATCH v2 0/5] Documentation: some coding guideline updates

> Hi,

> Changes compared to v1:
>
>   - Fix clang-format to use a single space to indent preprocessor
>     directives instead of using tabs. Thus, this series is now built
>     with kn/ci-clang-format at 1b8f306612 (ci/style-check: add
>     `RemoveBracesLLVM` in CI job, 2024-07-23) merged into v2.46.0.
>
>   - Adapt the coding guidelines accordingly to also only use a single
>     space for indentation of nested preprocessor directives.
>
>   - Adopt a proposal by Junio to more clearly spell out the relationship
>     between a subsystem `S`, `struct S` and its functions `S_<verb>()`.
>
>   - Document `S_clear()`-style functions. I have adopted the proposal by
>     Junio hear, where `clear = release + init` with the restriction that
>     `S_init()` must not allocate any resources.
>
>   - Add another patch on top that makes variable initializers consistent
>     in our coding guidelines. Our style is to add spaces between the
>     curly brace and the initializers (`struct foo bar = { something };`).
