title: Commit message prefix in git
body: <p>I have a requirement to prepend "ticket:N" to commit messages, where N is the number of the ticket I'm working on. But I keep forgetting about the prefix and remember about it only 5-6 commits later, so <code>--amend</code> won't help. Is it possible to set some warning, so git will warn me every time I forget to add the prefix?</p>
