Answer 1

To get git to not make a change when you are executing git commit --amend or git rebase -i.

Just delete the message (and save). All git does is look for a non empty message to see if a valid commit happened. Since there is a commit message (because you commited something before) git thinks that its a valid commit or rebase.
