[PATCH 00/10] tests: add and use a "test_hook" wrapper + hook fixes

This series is a test-only improvement series split up and adapted from a previous series of mine to add a "git init --no-template": https://lore.kernel.org/git/cover-00.13-00000000000-20211212T201308Z-avarab@gmail.com/

As the range-diff to that shows (with --creation-factor=50) all but one commit changed too much for "range-diff" to show it by default.

At the end of this series we have a "test_hook" that behaves like the existing "test_config", i.e. cleans up after itself (by default). See 08/10.

As also explained in 08/10 this means that it'll be much easier to thoroughly test the "config-based hooks" series, as everything that now writes hooks will go through this wrapper, and can be made to use the config-based hooks.

Along the way I found various issues in existing tests that tested our hooks, and fixed those issues.there were variou

  hook tests: turn exit code assertions into a loop
  t5540: don't rely on "hook/post-update.sample"
  tests: assume the hooks are disabled by default
  bugreport tests: tighten up "git bugreport -s hooks" test
  tests: indent and add hook setup to "test_expect_success"
  hook tests: get rid of unnecessary sub-shells
  fetch+push tests: have tests clean up their own mess
  test-lib-functions: add and use a "test_hook" wrapper
  tests: change "mkdir -p && write_script" to use "test_hook"
  tests: change "cat && chmod +x" to use "test_hook"
