Well, it’s truly more useful to provide long name atoms for the "log" family,
But if we need to establish a unified interface for --format, shouldn't
we extend it base on `ref-filter`?

At present, the scalability of the implementation in `ref-filter` is better,
but it does not support two-letter shorthands atoms...
