Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

まず、要求された tsconfig.json オプションを既存の tsc --showConfig の動作と比較します。最終的な設定と tsconfig.json のパスをどのように出力すべきかを確認し、その後、要求された設定とコンソール出力のカバレッジを追加します。この issue では具体的なファイルやテストは指定されていません。
