We clarified how clean.requireForce interacts with the --dry-run option in the previous commit, both in the implementation and in the documentation. Even when "git clean" (without other options) is required to be used with "--force" (i.e. either clean.requireForce is unset, or explicitly set to true) to protect end-users from casual invocation of the command by mistake, "--dry-run" does not require "--force" to be used, because it is already its own protection mechanism by being a no-op to the working tree files.
The previous commit, however, missed another clean-up opportunity around the same area. Just like in the "--dry-run" mode, the command in the "--interactive" mode does not require "--force", either. This is because by going interactive and giving the end user one more step to confirm, the mode itself is serving as its own protection mechanism.
Let's take things one step further, unify the code that defines interaction between `--force` and these two other options. Just like we added explanation for the reason why "--dry-run" does not honor `clean.requireForce`, add the same explanation for "--interactive". Finally, add some tests to show the interaction between "--force" and "--interactive" (we already have tests that show interaction between "--force" and "--dry-run").
