I used to work with a guy who wrote horrible commit messages. My (least) favorite was "works better." This was especially annoying because his code generally didn't go through review and was pushed into production within minutes. So any problem with the new code and we'd need to stare at the diff (which was often very complex) and try to answer the 3 questions in the article plus why it caused a problem.
Mind you - this was a guy with a few decades of experience.
Could be worse, at least he was claiming it was done. I frequently see several completely unrelated changes committed together with the comment "wip" (which stands for "work in progress") and these aren't from just one dev. Drives me nuts. "Was this finished?" "Did QA have any idea what you were sneaking in?"
