Hi Arash,
OK, I see. The commit that you shared improves the situation for
vc.el, except that I think 64 should be 66 (= 74 - 8). I attach what
I'm using, which also tells magit how long the summary should be.
Unfortunately, I don't see a way to set the fill-column in magit via
directory local variables (without eval). I've added the following
hack to my config:
(defvar git-fill-column-alist '(("auctex" . 66)))
(defun set-git-commit-fill-column ()
(when-let ((project (project-current))
(root (project-root project))
(name (file-name-nondirectory (directory-file-name root)))
(assn (assoc name git-fill-column-alist)))
(setq fill-column (cdr assn))))
(add-hook 'git-commit-mode-hook 'set-git-commit-fill-column)
Paul
