git-prune-script - Prunes all unreachable objects from the object database
git-prune-script [-n]
This runs git-fsck-cache --unreachable using the heads specified on the command line (or $GIT_DIR/refs/heads/* and $GIT_DIR/refs/tags/* if none is specified), and prunes all unreachable objects from the object database. In addition, it prunes the unpacked objects that are also found in packs by running git prune-packed.
Do not remove anything; just report what it would remove.
