!!! WARNING: RUST-ONLY HELPER !!! Resolve “is this subscript a range, and what are its bounds?” using the parse-time decision recorded by subscript_arg_split when one is available (c:Src/params.c:1533-1536 — C splits BEFORE expanding), and falling back to a depth-0 comma scan of the already-expanded text for the reference paths that do not record one.
