Get rid of all the boring git commit messages like 'small fix'

I'd rather have a tool that automatically caught every commit with an unsubstantial message and notified me that I might need to remind that programmer to be more descriptive with their commit messages. Even better if it provided a "wall of shame" of programmers in a repo to make them feel bad about writing unhelpful messages. That might get too simplistic (commit message quality doesn't correlate perfectly with length), but the point remains that I don't want to make it easier for them to replace trash with less obvious trash.
