These single quotes are funny; they close the test-snippet string, so
these variables are outside of any quoting (and thus subject to
whitespace splitting).

Yes, those quotes are funny, and I'm also aware that
they will be subjected to whitespace spliting.
But those quotes were intentional, they're there in order to have
better log with:

    ./t3900-i18n-commit.sh -v

With those funny quotes, we will see this (verbose) log:

    expecting success of 3900.38 'commit --fixup into ISO-2022-JP from UTF-8':
                git checkout -b fixup-ISO-2022-JP-UTF-8 C0 &&
                git config i18n.commitencoding ISO-2022-JP &&
                echo ISO-2022-JP >>F &&
                git commit -a -F "$TEST_DIRECTORY/t3900/ISO-2022-JP.txt" &&
                test_tick &&

                git commit -a --fixup HEAD^ &&
                git rebase --autosquash -i HEAD^^^ &&

                test_line_count = 3 actual &&
                iconv -f ISO-2022-JP -t utf-8 "$TEST_DIRECTORY/t3900/ISO-2022-JP.txt" >expect &&
                git cat-file commit HEAD^ >raw &&

I think it's easier to manual run the test step with this log.
