- Simplify `assert_buffer_eq!` logic. - Deprecate `assert_buffer_eq!`. - Introduce `TestBackend::assert_buffer_lines`. Also simplify many tests involving buffer comparisons. For the deprecation, just use `assert_eq` instead of `assert_buffer_eq`: ```diff -assert_buffer_eq!(actual, expected); +assert_eq!(actual, expected); ``` --- I noticed `assert_buffer_eq!` creating no test coverage reports and looked into this macro. First I simplified it. Then I noticed a bunch of `assert_eq!(buffer, …)` and other indirect usages of this macro (like `TestBackend::assert_buffer`). The good thing here is that it's mainly used in tests so not many changes to the library code.
