`geoip_format_bridge_stats()` generates the `bridge-stats` file contents, and if `country_data` is NULL then it writes "bridge-ips \n" to the file. Then when `validate_bridge_stats()` is called, if it can't find a populated `bridge-ips` line it tries to match "bridge-ips\n", which should always fail because of the extra whitespace that was added in `geoip_format_bridge_stats()`. Isn't that right? The only thing that confuses me is why this hasn't triggered so far. Maybe something in my analysis is incorrect, or the `bridge-stats` file is always generated after we accept a connection?
