[PATCH v5 0/8] [Newcomer] t7004: modernize the style

- Remove whitespace after the redirect operators.

- Move number of expect files prepared outside of
  test_expect_success to be inside the tests that use it.

- Split some lines that have two commands into two lines
  one command each.

- Turn some "<<\EOF" into "<<-\EOF" and indent their body.

- Avoid using pipes in the output from "test-tool ref-store"
  and write the output to a file.

- Change test_expect_success that are seperated from its name
  to be on the same line.

- Avoid separating test Description and test body with backslash

- Use single quotes instead of double quotes for test description and
  body.

- Use write_script which takes care of emitting the `#!/bin/sh` line
  and the `chmod +x`.

There are still tests that could lose exit status to pipe. This needs to be modernized too, I will fix them in another patch series.
