(Cannot be combined +with `--stdin-commits` or `--reachable`.) ++ +With the `--stdin-commits` option, generate the new commit graph by +walking commits starting at the commits specified in stdin as a list +of OIDs in hex, one OID per line. (Cannot be combined with +`--stdin-packs` or `--reachable`.) ++ +With the `--reachable` option, generate the new commit graph by walking +commits starting at all refs.
