I took a look and it’s set for log-edit-mode only. It would be nice if magit can pick it up. I’m sure a lot of people (me included) use magit for developing Emacs. The only problem is magit’s commit message editing buffer doesn’t have a special major mode. It does git-commit-mode which is a minor mode, and runs git-commit-setup-hook. But I’m not sure how to edit dir-locals to set fill-column using a hook or minor mode.
