# A use case is to automate interactive rebase by putting the current fixup commit with the commit
# where the same file was last changed, e.g.
# ❯ for f in $(git status -uno --porcelain | awk -F ' ' '{print $2}'); do git add $f && amend-fixup $(git --no-pager log -n 1 --pretty=format:%H -- $f); done
amend-fixup() {
    SHA=$1
    git commit --fixup $SHA &&
        GIT_EDITOR="cat" git rebase --autosquash --autostash --interactive $SHA^
