Thank you for this perspective: I never realized that "git bisect" is good only as long as commit messages are meaningful. I'm going to teach how to use "git" in my class next semester, and this is surely a point I will make!

I may have poorly made my point. It isn't that bisect is /only/ useful with good commit messages, but many subcommands are vastly improved when there is meaningful information about the change in the message.

For example, rebase's default output includes the previous and next commit messages when you pause to edit a commit.
