Yup. Thanks. The only thing that makes me wonder is why any of the existing tests (among which I think I saw range-diff driven from format-patch) did not catch this rather obvious glitch. > diff --git a/t/t3206-range-diff.sh b/t/t3206-range-diff.sh > index e497c1358f..048feaf6dd 100755 > --- a/t/t3206-range-diff.sh > +++ b/t/t3206-range-diff.sh > @@ -248,18 +248,24 @@ test_expect_success 'dual-coloring' ' > for prev in topic master..topic > do > test_expect_success "format-patch --range-diff=$prev" ' > - git format-patch --stdout --cover-letter --range-diff=$prev \ > + git format-patch --cover-letter --range-diff=$prev \ > master..unmodified >actual && Ah, of course. Then the "actual" file gets the names of the output files; we expect to see 5 of them. But now we have lost all the range-diff tests run under "--stdout", so next time some other change regresses only that codepath, we will not notice (which is fine for now but would want to be addressed before the end of the year around which time we certainly will all forget).
