Add commit hook and make the verification customizable.
There are three hooks: - 'pre-commit' is given an opportunity to inspect what is being committed, before we invoke the EDITOR for the commit message; - 'commit-msg' is invoked on the commit log message after the user prepares it; - 'post-commit' is run after a successful commit is made. The first two can interfere to stop the commit. The last one is for after-the-fact notification. The earlier built-in commit checker is now moved to pre-commit. Signed-off-by: Junio C Hamano <junkio@cox.net>

+# An example hook script to verify what is about to be committed.
+# Called by git-commit-script with no arguments. The hook should
+# exit with non-zero status after issuing an appropriate message if
+# it wants to stop the commit.
+#
+# To enable this hook, make this file executable.
+
+# This is slightly modified from Andrew Morton's Perfect Patch.
+# Lines you introduce should not have trailing whitespace.
+# Also check for an indentation that has SP before a TAB.
