Can comment notifications get different subject lines? Perhaps if a comment has no individual title, the subject line could be "Re:<original post title>"?

The reason I ask is that GMail groups all emails with the same subject line (e.g. "Reply to your comment.") and sender (e.g. dw_null@dreamwidth.org) under one "conversation". This makes all Dwth comments that don't have individual titles get grouped together in a nonsensical and confusing manner. Frustratingly, the GMail people are religiously against making the "conversation" feature optional, so only Dwth can stop the madness. *scowl*
