You were right on this, and I updated the patch to match the feedback. Braced-init commenting is now option-based (`CommentAnonymousInitLists` and `CommentTypedInitLists`, both default `false`) rather than always on, so it stays consistent with the existing `Comment*` knobs. I also moved the GH171842 cases into a separate `argument-comment-init-list.cpp`, updated the docs and release notes accordingly, and addressed the smaller nits from review. 

@vbvictor @maflcko @localspook Please take a look
