For some content, such as verify_default_secure_settings, the CCE's are
each tied to an individual line in the same file. This level of granularity
would require creating a rule for each line:
ftp_passive on
ftp_sanitycheck on
check_hostnames on
request_header_max_size 20 KB
reply_header_max_size 20 KB
cache_effective_user squid
cache_effective_group squid
ignore_unknown_nameservers on

I don't believe it does, or at least the lines in /etc/init.d/squid and
/etc/squid/squid.conf are not the way that the prose recommends them
to be.
