Have you tried this?

git log --pretty=oneline --abbrev-commit

The problem is probably that you are missing an empty line after the first line. The command above usually works for me, but I just tested on a commit without empty second line. I got the same result as you: the whole message on one line.

Empty second line is a standard in git commit messages. The behaviour you see was probably implemented on purpose.

The first line of a commit message is meant to be a short description. If you cannot make it in a single line you can use several, but git considers everything before the first empty line to be the "short description". oneline prints the whole short description, so all your 3 rows.
