hot_standby_feedback and max_standby_archive_delay

Hi,

Myself and others found this statement in the documentation about
$SUBJECT very confusing: "max_standby_archive_delay must be kept large
in this case, because delayed WAL files might already contain entries
that conflict with the desired standby queries.".  After a chat with
Andres I've tried to make it clearer what said statement tries to convey.

Did I succeed?
