t1100: modernize test style

The tests in this script use the old style in which the test title and
body are passed as separate backslash-continued arguments, with bodies
indented using spaces:

    test_expect_success \
        'title' \
        'body'

Convert them to the modern style in which the body is a single-quoted
block on its own lines, indented with a tab:

    test_expect_success 'title' '
        body
    '

While at it, remove an extraneous blank line between two tests.

This is a style-only change; no test logic is modified.
