Problem - `redir_exec` is obsolete, but it keeps getting used in new tests because people copy existing tests. - Disadvantages of `redir_exec`: - Captures extra junk before the actual error/message that we _want_ to test. - Does not fail on error, unlike e.g. `command()`. Solution - Use new functions like `nvim_exec` and `pcall_err`.
