The string literals "%" and "\%" produce the same string. Without
fundamentally changing the way the language works, printf can't behave
differently on one or the other.
So the real behavior change is in what "% |" and "%\n" do. It's a
little weird that the new code consumes an argument before giving up and
printing "%", but it has every right to do something weird on invalid
input like that.
