Incorrect Position returned from new CodedInputStream.Position property

What steps will reproduce the problem?
1. Create a CodedInputStream on a System.Stream object.
2. Read a length delimited prefix
2. Call CodedInputStream.PushLimit(0)
3. Position property returns incorrect value

What is the expected output? What do you see instead?

The bufferSizeAfterLimit field should be taken into account when computing the 
stream offset.

The following change should be applied to address the issue.

    get
    {
        if (input != null)
-           return input.Position - (bufferSize - bufferPos);
+           return input.Position - ((bufferSize + bufferSizeAfterLimit) - 
bufferPos);
        return bufferPos;
    }
