The prepare-commit-msg hook is run whenever a "fresh" commit message is prepared, just before it is shown in the editor (if it is). Its purpose is to modify the commit message in-place. It takes one to three parameters. The first is the name of the file that the commit log message. The second is the source of the commit message, and can be: "message" (if a -m or -F option was given); "template" (if a -t option was given or the configuration option commit.template is set); "merge" (if the commit is a merge or a .git/MERGE_MSG file exists); "squash" (if a .git/SQUASH_MSG file exists); or "commit", followed by a commit SHA1 as the third parameter (if a -c, -C or --amend option was given). If its exit status is non-zero, git-commit will abort. The hook is not suppressed by the --no-verify option, so it should not be used as a replacement for the pre-commit hook. The sample prepare-commit-msg comments out the `Conflicts:` part of a merge's commit message; other examples are commented out, including adding a Signed-off-by line at the bottom of the commit messsage, that the user can then edit or discard altogether.
