Hello, i found some error related to indentation and it seems worth it to solve.
In google style guide, there is the contents for namespace indentation
https://google.github.io/styleguide/cppguide.html#Namespace_Formatting
Specifying 'the contents of namespace are not indented'.
For example,

You can see there is indent inside in namespace scope.
This is not fit to google style guide.

This is the example of correct style refer to google style guide.
And as you can see,

lint is not catching!
I think it would be great that if this problem solved.
Can anyone give comments or feedback for this issue?
Thankyou!
