In es/format-patch-rangediff, we added a '--range-diff' option to git-format-patch to automatically add a range-diff. We also added an option to write the diff as commentary to a single patch submission. However, this check was not tested. I discovered this test gap by running 'make coverage-test coverage-report' on 'next' and then comparing the uncovered lines with those in the diff between 'master' and 'next'. I have a script that automates this process, and I'm still working on polishing it. You can see an earlier version at [1].
