[PATCH 2/4] t5600: modernize style

[Jeff King <peff@peff.net>]

This is an old script which could use some updating before
we add to it:

  - use the standard line-breaking:

      test_expect_success 'title' '
              body
      '

  - run all code inside test_expect blocks to catch
    unexpected failures in setup steps

  - use "test_commit -C" instead of manually entering
    sub-repo

  - use test_when_finished for cleanup steps

  - test_path_is_* as appropriate
