;;; Commentary:
;; This package assists the user in writing good Git commit messages.
;; While Git allows for the message to be provided on the command
;; line, it is preferable to tell Git to create the commit without
;; actually passing it a message. Git then invokes the `$GIT_EDITOR'
;; (or if that is undefined `$EDITOR') asking the user to provide the
;; message by editing the file ".git/COMMIT_EDITMSG" (or another file
;; in that directory, e.g. ".git/MERGE_MSG" for merge commits).
;; When `global-git-commit-mode' is enabled, which it is by default,
;; then opening such a file causes the features described below, to
;; be enabled in that buffer. Normally this would be done using a
;; major-mode but to allow the use of any major-mode, as the user sees
;; fit, it is done here by running a setup function, which among other
;; things turns on the preferred major-mode, by default `text-mode'.
;; Git waits for the `$EDITOR' to finish and then either creates the
;; commit using the contents of the file as commit message, or, if the
;; editor process exited with a non-zero exit status, aborts without
;; creating a commit. Unfortunately Emacsclient (which is what Emacs
;; users should be using as `$EDITOR' or at least as `$GIT_EDITOR')
;; does not differentiate between "successfully" editing a file and
;; aborting; not out of the box that is.
;; By making use of the `with-editor' package this package provides
;; both ways of finish an editing session. In either case the file
;; is saved, but Emacseditor's exit code differs.
;;
;; C-c C-c Finish the editing session successfully by returning
;; with exit code 0. Git then creates the commit using
;; the message it finds in the file.
;;
;; C-c C-k Aborts the edit editing session by returning with exit
;; code 1. Git then aborts the commit.
;; Aborting the commit does not cause the message to be lost, but
;; relying solely on the file not being tampered with is risky. This
;; package additionally stores all aborted messages for the duration
;; of the current session (i.e. until you close Emacs). To get back
;; an aborted message use M-p and M-n while editing a message.
;;
;; M-p Replace the buffer contents with the previous message
;; from the message ring. Of course only after storing
;; the current content there too.
;;
;; M-n Replace the buffer contents with the next message from
;; the message ring, after storing the current content.
;; Some support for pseudo headers as used in some projects is
;; provided by these commands:
;;
;; C-c C-s Insert a Signed-off-by header.
;; C-C C-a Insert a Acked-by header.
;; C-c C-t Insert a Tested-by header.
;; C-c C-r Insert a Reviewed-by header.
;; C-c C-o Insert a Cc header.
;; C-c C-p Insert a Reported-by header.
;; C-c M-s Insert a Suggested-by header.
;; When Git requests a commit message from the user, it does so by
;; having her edit a file which initially contains some comments,
;; instructing her what to do, and providing useful information, such
;; as which files were modified. These comments, even when left
;; intact by the user, do not become part of the commit message. This
;; package ensures these comments are propertizes as such and further
;; prettifies them by using different faces for various parts, such as
;; files.
;; Finally this package highlights style errors, like lines that are
;; too long, or when the second line is not empty. It may even nag you
;; when you attempt to finish the commit without having fixed these
;; issues. Some people like that nagging, I don't, so you'll have to
;; enable it. Which brings me to the last point. Like any
;; respectable Emacs package, this one too is highly customizable:
