From d1cc130a5eb50d5bfe1e8b76cab3d8970fd70ad1 Mon Sep 17 00:00:00 2001
From: Steven Grimm <koreth@midwinter.com>
Date: Sun, 22 Jul 2007 21:17:42 -0700
Subject: Teach git-commit about commit message templates.

These are useful in organizations that enforce particular formats
for commit messages, e.g., to specify bug IDs or test plans.
Use of the template is not enforced; it is simply used as the
initial content when the editor is invoked.
