Title: %f is not available for git-log for git 1.5.5.6. %s and %f are almost same.

Commit messages are not printed for git 1.5.5.6 (that's what I have on my VPS) because %f is not available for git-log format. %s is available and since we are not using the subject for naming a file, we can safely use %s.
