… r=compiler-errors Explain why we require `_` for empty patterns This adds a note to the "non-exhaustive patterns" diagnostic to explain why we sometimes require extra `_` patterns on empty types. This is one of the two diagnostic improvements I wanted to do before [stabilizing `min_exhaustive_patterns`](rust-lang#122792). r? `@compiler-errors`
