Merged

This is a minor refactor of how `_warn_use_shell` can be, and is, invoked. The `_warn_use_shell` helper function in `git.cmd` takes a single `bool`-valued argument `extra_danger`, which is conceptually associated with having a `True` value of `USE_SHELL`, but the association is not necessarily obvious. Specifically: - For the warning given when reading `USE_SHELL` on the `Git` class or through an instance, `extra_danger` is always `False`. This is so even if the `USE_SHELL` value is currently `True`, because the danger that arises from `True` occurs internally. - For the warning given when writing `USE_SHELL`, which can only be done on the `Git` class and not on or through an instance, `extra_danger` is the value set for the attribute. This is because setting `USE_SHELL` to `True` incurs the danger described in gitpython-developers#1896. When reading the code, which passed `extra_danger` positionally, the meaning of the parameter may not always have been obvious. This makes the `extra_danger` parameter keyword-only, and passes it by keyword in all invocations, so that its meaning is clearer.
