Subject: [PATCH] Tweak code coverage logic
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- make OS detection looser to exclude more Linux files on macOS (and
  vice versa)
- Allow slight (0.5%) coverage drops to account for somewhat random
  fluctuations.
