Feel free to add an extended explanation into the body of the commit
message. It makes it easier than having to refer back to Jira tickets and pull
requests.
I think @zwoop may have been referring to the PR subject, which should
generally be the same as the leading commit. The PR subject shows up as a merge
commit so it is worth making it nice :)
