Do you know how to rebase changes locally? I'd assume you'd have a local branch where you have one commit per review you post. Then you create one diff per commit and then show these for review. My nitpicks should then be squashed into the commits and the diff reuploaded...

If I detach head to commit "on different branch" - I guess git will forget about detached head and lose history (or simply refuse to perform one of required steps)

stackoverflow helped, still don't know how to squash them, but history is modified in a way i expeced
