Hello, Just wanted to report that I am running into issues with the git 2.26 `rebase.backend` change. I am a maintainer on https://github.com/FredrikNoren/ungit which is a UI for git using a http server / browser architecture. We are using `git rebase` in non interactive mode (e.g. not specifying `-i` or `--interactive`) on the server and with git 2.26 this fails because it seems that it now runs in interactive mode by default. It tries to an editor on `git rebase --continue`. Specifying `-c rebase.backend=apply` fixes our issue see https://github.com/FredrikNoren/ungit/issues/1301 It would be great if the new merge backend would also support a non interactive mode e.g. by respecting the `-i` or `--interactive` option, Thanks and regards Bastian Buchholz
