Thank you for filling out a Git bug report! Please answer the following questions to help us understand your issue. What did you do before the bug happened? (Steps to reproduce your issue) git init test cd test echo "test" > test.txt git add -AN git add -p What did you expect to happen? (Expected behavior) The file would be added to staged changes after confirming each individual change in an interactive mode. What happened instead? (Actual behavior) I get "error: test.txt: already exists in index". What's different between what you expected and what actually happened? The file wasn't added to staged changes. Anything else you want to add: It used to work before updating to 2.28, previous version was 2.26 if I'm not mistaken. I couldn’t find any mention of changes in the recent release notes. Please review the rest of the bug report below. You can delete any lines you don't wish to share.
