I see that the system [automatically adds "possible duplicate of..." links](https://meta.stackexchange.com/questions/44173/autocomment-when-voting-to-close-as-duplicate) when voting to close as a duplicate.

Earlier today, I voted to close [Why is SVN better than VSS?](https://stackoverflow.com/questions/2649260/why-is-svn-better-than-vss) as a duplicate of [SVN? VSS? Why is one better than the other?](https://stackoverflow.com/questions/306339/svn-vss-why-is-one-better-than-the-other), and a suitable comment was added. I thought that comment would be valuable no matter what the close resolution ended up being. However, the question was ultimately closed as "subjective and argumentative", and the auto-added "possible duplicate" comment was removed!

I suggest that automatic "possible duplicate" comments *only* be removed if the question is actually closed as a duplicate. Otherwise, that useful information is lost.
