As noted in 43dafc4172 ("format-patch: don't include --stat with
--range-diff output", 2018-11-22) the diff options provided on the
command-line currently affect both the range-diff and the patch
output, but there was no test for checking this with output where we'd
show a patch diff. Let's add one.
