I was also going to suggest squashing the repetition. Here's what I
had in mind:

--- >8 ---
test_foldcase() {
        ignore=$1 &&
        case "$2" in
        true) fold=--fold-case folded=true ;;
        false) fold=--no-fold-case folded=false ;;
        *) fold= folded=$ignore ;;
        esac &&
        case $folded in true) folded=a ;; false) folded=A ;; esac &&

        test_expect_success "V: case folding: ignorecase=$ignore${fold:+ 
$fold}" "
                git -c core.ignorecase=$ignore fast-import $fold <input &&
                git ls-tree refs/heads/V >actual &&
                git update-ref -d refs/heads/V &&
                cat >expect <<-EOF &&
                100644 blob 78981922613b2afb6025042ff6bd878ac1994e85    $folded
                EOF
                test_cmp expect actual
        "
}

for o in '' true false
do
        for c in true false
        do
                test_foldcase $c "$o"
        done
done
--- >8 ---

which outputs:

--- >8 ---
ok 176 - V: case folding: ignorecase=true
ok 177 - V: case folding: ignorecase=false
ok 178 - V: case folding: ignorecase=true --fold-case
ok 179 - V: case folding: ignorecase=false --fold-case
ok 180 - V: case folding: ignorecase=true --no-fold-case
ok 181 - V: case folding: ignorecase=false --no-fold-case
--- >8 ---
