Subject: [PATCH] util: inspect __proto__ key as written in object literal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Since util.inspect() gives object-literal-like output, handle the
special `__proto__` key in the way that it would be handled in object
literals.
