Thanks for submitting a PR, your contribution is really appreciated!

Here's a quick checklist that should be present in PRs (you can delete this text from the final description, this is
just a guideline):

- [ ] Create a new changelog file in the `changelog` folder, with a name like `<ISSUE NUMBER>.<TYPE>.rst`. See [changelog/README.rst](https://github.com/pytest-dev/pytest/blob/master/changelog/README.rst) for details.
- [ ] Target the `master` branch for bug fixes, documentation updates and trivial changes.
- [ ] Target the `features` branch for new features and removals/deprecations.
- [ ] Include documentation when adding new features.
- [ ] Include new tests or update existing tests when applicable.

Unless your change is trivial or a small documentation fix (e.g.,  a typo or reword of a small section) please:

- [ ] Add yourself to `AUTHORS` in alphabetical order;
