Re: [PATCH v2 0/8] cherry-pick: add `--empty`

> The ultimate goal of this series is to allow git-cherry-pick(1) to
> automatically drop redundant commits. The mechanism chosen is an
> `--empty` option that provides the same flexibility as the `--empty`
> options for git-rebase(1) and git-am(1).

> Some secondary goals are to improve the consistency in the values and

>    docs: address inaccurate `--empty` default with `--exec`
>    docs: clean up `--empty` formatting in git-rebase(1) and git-am(1)
>    rebase: update `--empty=ask` to `--empty=drop`
>    sequencer: treat error reading HEAD as unborn branch
>    sequencer: do not require `allow_empty` for redundant commit options
>    cherry-pick: decouple `--allow-empty` and `--keep-redundant-commits`
>    cherry-pick: enforce `--keep-redundant-commits` incompatibility
>    cherry-pick: add `--empty` for more robust redundant commit handling
