Import-Styles.md - clarify country_code key

[mtmail]

I'm also not sure about the example

    local flex = require('import-full')

    function osm2pgsql.process_relation(object)
        if object.tags.boundary ~= 'administrative' or object.tags.admin_level ~= '2' then
          flex.process_relation(object)
        end
    end

When I added a debug statement to the function it was never called even though the input had relations. Should it be flex.process_relation?

Now, how do I convert this into an issue?

Retested the example replacing process_relation and it works as expected for me.
