Here is a trick I have learnt to use with my emacs configuration for
commit messages:
;; Git settings: auto-fill-mode for commits with dedicated mode.
(define-derived-mode git-commit-mode text-mode "GitCommit"
"Mode for writing git commit files."
(setq fill-column 72)
(auto-fill-mode +1)
(set (make-local-variable 'comment-start-skip) "#.*$"))
(add-to-list 'auto-mode-alist
'("/\\(?:COMMIT\\|NOTES\\|TAG\\|PULLREQ\\)_EDITMSG\\'"
. git-commit-mode))
This forces any commit messages written to be within 72 characters, so
you have one thing less to think about. Just be careful to keep
discussion links into one line.
