Hi,
While running the 2.22.0-rc1 tests on Fedora, I hit a few
new test failures since 2.21.0 -- but only on the s390x
architecture.
I haven't had time to dig into these the past few days, so I
thought I would send what I do have in case the problem is
obvious to someone else. I think all of the failing tests
are due to `git diff` commands.

The test output from '-x --verbose-log' is quite verbose and
the issues are often in whitespace/end-of-line which might
be mangled by some MTA/MUA. So the output is at:
https://tmz.fedorapeople.org/git-2.22.0-rc1-s390x-failures (327K)
I don't have direct access to these s390x builders. I may
be able to arrange shell access (or even reproduce this with
qemu's s390x emulation).
Before I go further down that road, I wanted to see if this
output might be enough to point to the problem. If not, I
can run the failing tests with the --debug option and save
the trash directory (unless I can get more direct access to
the s390x builder to be able to bisect).
I rebuilt git-2.21.0 on the same s390x builder successfully,
so I don't think this issue is a bug in another of the
packages in the current Fedora tree. But it's certainly
possible that git-2.22.0-rc1 is just tickling a real bug in
some other tool/library on s390x.
Thanks for any help in narrowing this down.
