Going forward, if I made changes to my private repository (containing the "before" and "after" parts) and pushed to the public repository (containing only the "after" part), would this only push the commits in the "after" part? Essentially, I want to develop in my private repository and see my "before" and "after" changes when I "git log/show", but only push the "after" changes to the public repository.

I've also been looking into private branches. Could I do something like keep my "before" changes on a private branch, and then do all future development on a public branch?

Thanks for the pointer to git grafts, I'll have to read up on it further.
