Hi, agree with Mathieu: I prefer keeping issue id in footer (at the end of commit message) so we can save some characters in subject line to express something meaningful.
In addition if we put this information in commit footer (or body) we can copy the complete link to issue (for example https://issues.apache.org/jira/browse/OFBIZ-4274 instead of just OFBIZ-4274) so that we can just "click" on it to display related issue :) But like Mathieu said, I don't mind if some people find this `OFBIZ-XXX` so meaningful that they want to keep it on subject line.
