In-Reply-To: <pull.1016.git.1628842990.gitgitgadget@gmail.com>

From: ZheNing Hu <adlternative@gmail.com>

parse_ref_filter_atom() checks whether the type of the atom is ATOM_SYMREF, this is not necessary for other atoms. So add the symref_atom_parser() specifically to parse the atom, and set need_symref in it. This can make the program logic more concise.
