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.

It was an intentional (though unjustified) oversight. Thanks for
working on this.

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.

Interesting. Does your script detect that the --creation-factor option
added by patch 13/14 [1] also lacks a test? (I'm not necessarily
suggesting adding a test at the moment. Even Dscho's git-range-diff
series doesn't have a test for "creation factor", so it wouldn't
necessarily make sense to add a test only for the git-format-patch
case. Instead, we'd want, at some point, to add tests covering both
git-range-diff and git-format-patch.)
