kill ring questions, #emacs

[Emanuel Berg]

I just posted this on #emacs but I don't see
why I can't post it here as well. They say in
the topic "No public logging! What happens in
#emacs stays in #emacs" but surely that doesn't
refer to 100% on-topic Q&As, right? (Or, for
that matter, the topic itself :))

<incal> hello, is there a setting to inhibit
        the kill ring from filling up with
        several back-to-back instances of the
        same string?
        
<incal> also why is the kill ring fontified?
        why not let that be determined by the
        mode/context of the new place, where it
        is yanked?
