Suppose you have the following code: ``` if (box_depth > max_depth) // limit the depth to max { box_depth = max_depth; } ``` after applying readability-use-std-min-max, the code is: ``` box_depth = std::min(box_depth, max_depth); ``` the explaining comment is dropped. The expected code is: ``` box_depth = std::min(box_depth, max_depth); // limit the depth to max ```
