"git commit --amend" is (also) the way to edit the last commit message,
and for that you need to be able to do an "empty" amend.

In your example above, git will also tell you that you have unstaged
changes to readme.txt.

If that isn't enough, you can use "-v" to display the diff in the editor
(and remove it).
