The "`TT_PointerOrReference` token (`*`, `&`, or `&&`) before a declarator" part meant something like `int * foo;` in my mind, and breaking after the `*` makes more sense to me.

Yes, I'd break before the `*` instead of after it. (You can't break after the `const` because of the column limit.)

If the column limit permits, I have no opinion on whether to break before the `*` or after the `const` because the `*` is not (immediately) before the declarator.
