feat: empty commits

[uhthomas]

We have a workflow where to prune resources in Kubernetes, we need to create an empty git commit with a specific message. It doesn't look like there's any way to do this in Sapling?

Try --config ui.allowemptycommit=true ?

Yeah, that worked, thank you! I couldn't find this anywhere in the documentation, or issues.
