    +    It is worth notice that albeit all executable script strings
    +    are changed to use single quotes (for modern style uniformity),
    +    some of the test titles are kept untouched, e.g.
    +
    +    -       test_expect_success \
    +    -           "adding test file $p and Z/$p" \
    +    -           'git update-index --add $p &&
    +    -           git update-index --add Z/$p'
    +    +       test_expect_success "adding test file $p and Z/$p" '
    +    +           git update-index --add $p &&
    +    +           git update-index --add Z/$p
    +    +    '
    +
    +    see the "adding test file $p and Z/$p" part.
    +
    +    This is because the test title is simply echo'd/print'd, and
    +    double quotes are necessary for "$p" interpolation; however,
    +    the test body (executable script string) gets eval'd, and
    +    single quotes are acceptable in this case.
    +
         Update the style for uniformity.

         As Documentation/CodingGuidelines says, our shell scripts
    -    (including tests) are to use HT for indentation, but this script
    -    uses 4-column indent with SP. Fix this.
