Re: Aborting 'rebase main feat' removes unversioned files

Just tested it on my MacBook. To my surprise, the file got deleted by
'git rebase main feat':

550$ git --version
git version 2.33.0

551$ git init -b main
Initialized empty Git repository in
/Users/ted/workspace/git-abort-bug/test/.git/

552$ git commit -m 'init' --allow-empty
[main (root-commit) ede7bdf] init

553$ git checkout -b feat
Switched to a new branch 'feat'

554$ echo 123 > readme.txt

555$ git add readme.txt

556$ git commit -m 'txt=123'
[feat 29ac3de] txt=123
 1 file changed, 1 insertion(+)
 create mode 100644 readme.txt

557$ git checkout main
Switched to branch 'main'

558$ echo 012 > readme.txt

559$ git rebase main feat
Current branch feat is up to date.

560$ git rebase --abort
fatal: No rebase in progress?

is that I cannot reproduce it...
Looks like it occurs only in one git version (2.31.0.windows.1, IIRC).
And it does not occur in the latest git version: git version 2.33.0.windows.2.

Looks like a bug in git rebase main feat.

To reproduce:
git init
git commit -m 'init' --allow-empty
git checkout -b feat
echo 123 > readme.txt
git add readme.txt
git commit -m 'txt=123'
git checkout main
echo 012 > readme.txt
git rebase main feat
git rebase --abort

Did you forget committing?

I don't think so.

The point is that "readme.txt" is not a tracked file on the main branch,
and thus Git should consider it precious.

I don't think the "rebase --abort" is the problem here, though. It's the
command before:

  git rebase main feat

The "feat" branch is already ahead of "main" (which has no new commits),
and so it just says:

  Current branch feat is up to date.

and leaves us on the "feat" branch. But in doing so, it overwrites the
precious untracked content in the working tree.

The "git rebase --abort" command then does nothing, because there's no
rebase in progress.
