We indent by four spaces in line continuations :)

Here and also in other C++ files.

We usually use env->as_external() for the parameter right here, so that we can get access to the Environment object in the callback itself. Again, here and below.

You mean instead of Local<Value>()?

Yes.The same also needs to be done for all other such instances, otherwise I'm fairly sure some tests will fail because of this.

Tests completed fine with just Local<Value>(), so that's a bit worrying, but it's perhaps out of the scope of this PR to add tests for that. I've now switched to env->as_external wherever it was previously used.

Similar tests should exist for Object.getOwnPropertyDescriptor(crypto.SecureContext.prototype, '_external') and Object.getOwnPropertyDescriptor(crypto.Connection.prototype, '_external') where crypto = process.binding('crypto'), and Object.getOwnPropertyDescriptor(process.binding('udp_wrap').UDP.prototype, 'fd').
