What did you do before the bug happened? (Steps to reproduce your issue)
mkdir test cd test git init touch test git add test git commit -m 'init' podman run --rm -it -v `pwd`:/git:z --entrypoint sh docker.io/alpine
> container# apk add git > container# cd /git > container# git diff-index --quiet HEAD -- ; echo $?
1
> container# git diff-index --quiet HEAD -- ; echo $?
1
> container# git status
On branch master nothing to commit, working tree clean
> container# git diff-index --quiet HEAD -- ; echo $?
0
What did you expect to happen? (Expected behavior) `git diff-index --quiet HEAD -- ; echo $?` should return `0` even without executing `git status`.
What happened instead? (Actual behavior) Without executing `git status` `git diff-index --quiet HEAD -- ; echo $?` will repeatedly print `1`.
What's different between what you expected and what actually happened? It is odd that `git diff-index --quiet HEAD -- ; echo $?` prints different results depending on whether `git status` was executed.
Anything else you want to add: Perhaps this has to do with running git in a container?
