The %>A log code is still tied to old logging state instead of the IP
values updated by PROXY protocol.

The only way I can see to log that value without patching Squid is with
something complicated like an external_acl_type helper to do the lookup
and supply it as a tag or note to Squid.

If you are happy to patch I can make a PR for you to try.
