Github Gists are close enough to what you describe sans the interactive rebase. You can create multiple files at once, all edits made in the web interface are committed to the repo, and all of it can be cloned and used with "real" git at any point.

Really? Are GitHub gists actual git repositories? Why no one says a line about it? What is the repo URL?

The "Embed: " button to the left of the embed URL is actually a dropdown, where you can switch to the clone URLs.
