This is a nice paragraph, but it might make sense to connect it to the commit's oneline somehow. I, for one, was surprised to see the oneline talk about `git commit` and the commit message about `git cherry-pick`. I could imagine that an introductory paragraph, talking about why one might want to commit empty commits, might be the best lead into the subject, and the paragraph about `cherry-pick` could follow (and be introduced by saying something along the lines that this config setting has more reach than just `git commit`; it also affects `git cherry-pick`)?
