I want to find out who created a branch.
I am sort of able to do so with:
git branch -a | xargs -L 1 bash -c 'echo "$1 `git log --pretty=format:"%H %an" $1^..$1`"' _
However, this returns the last committer per branch, not necessarily the person who created the branch.
List remote Git branches by author sorted by committer date:
git for-each-ref --format='%(committerdate) %09 %(authorname) %09 %(refname)' --sort=committerdate
