In #2843, it's requested that these trailing contextual lines should be
displayed as non-matching because they exceed the limit. While
reasonable, I think that:
1. This would be a weird complication to the implementation.
2. This would overall be less intuitive and more complex. Today, there
is never a case where ripgrep emits a matching line in a way where
the match isn't highlighted.
Closes#2843
