@mjsax, most likely it happened by accident but it's good practice to
separate the git commit subject from the body by inserting a line break. That
way, git can show you a nice one line git history `git log --oneline` without
seeing the body of the commit message. Also some other tools format the git log
nicely if one follows this rule.
