Description

Here is example output from a failed invocation  of `archery lint --cmake-format`:
 
INFO:archery:Running cmake-format linters
ERROR _main_.py:618: Check failed: /arrow/cpp/cmake_modules/ThirdpartyToolchain.cmake
 
It would be helpful to get the error details on failure, e.g., as a diff output like for C++. Granted, this may be low priority since `archery lint --cmake-format --fix` fixes the errors.
