I actually don't believe this can be done well enough to be useful,
i.e. with high-enough true positive rate and low enough false positive
rate.  Whether a commit log message is good or bad is basically a
human judgment call; software-based solutions for that, if at all
possible, can only be based on machine-learning techniques, which
INSHO would be a ridiculously expensive solution for such a simple
problem.
