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

```

I don't think --interactive is relevant here; the features triggered by
that option (i.e., the ability to tweak the instruction list) are
different from the notion that rebase would never interact with the user
at all.

There's more discussion of this change in the thread at:

  https://lore.kernel.org/git/20200310174017.GA549010@coredump.intra.peff.net/

The simplest fix is likely to set GIT_EDITOR=: in your environment when
you don't want the user to ever be presented with an editor.

Yes, the issue we have is the same described in the other thread.
I will try using GIT_EDITOR=: instead.

Thanks!
