Yep, whenever they fix a bug it’s added in a new flag that nobody knows about.

git --enable-sane-behaviour

As a casual git user I imagine the process normally goes something like this:

1. Development happens.
2. New feature makes it into the release version of git.
3. New version makes it into the various linux distro repositories.
4. People who run big git repos install the update.
5. Serious nerds hear about it and use the feature.
6. Many years pass.
7. I learn about it, if it’s widely used enough.

U are the only one who knows my pain

it’s not recommended to boast about your ignorance.
