Thanks for studying the code of Git. It will help the project in
bettering the code.
Welcome to the Git community!
Which version do you mean by "latest release" ?

Thanks a lot for this suggestion and the suggestions in the attachment.
However these are less than optimal to consume for the project.
Care to make these changes as actual commits in your local repository

See Documentation/SubmittingPatches
https://github.com/git/git/blob/master/Documentation/SubmittingPatches
Thanks,
Stefan
