This passes for me, on both cygwin and MinGW.

After adding a test_pause to test #6:

$ ./t3032-merge-recursive-options.sh -v

...

expecting success:
        q_to_cr <<-\EOF >expected &&
            justice and holiness and is the nurse of his age and theQ
        EOF

        git read-tree --reset -u HEAD &&
        git merge-recursive --ignore-space-change HEAD^ -- HEAD remote &&
        grep "justice and holiness" text.txt >actual &&
        test_cmp expected actual &&
        test_pause
