39e388728 (merging git rebase -i exec support) broke the funny names test in t3404-rebase-interactive.sh:

    expecting success:
            git rev-list A..funny >expect &&
            test_tick &&
            FAKE_LINES="1 2 3 4" git rebase -i A &&
            git rev-list A.. >actual &&
            test_cmp expect actual

    rebase -i script before editing:
    pick f6fec15 end with slash\
    pick 4f2ade4 something (\000) that looks like octal
    pick f95dfbf something (\n) that looks like a newline
    pick 0e82af6 another commit
