It is a real pain if you make a commit that has the wrong ticket number prefix - you end up needing to do a bunch of manual work to reconcile the various places things got logged incorrectly to paper over the mistake.

Since we are adding validation for commit messages in other ways (formatting, etc.) we should see if it would be possible to also validate against JIRA that the ticket you are nominally committing to makes sense: is open, is assigned to you, etc.
