Whenever someone asks what to do with code that is no longer needed the answer is usually "delete it, restore it from source control if you need it back".

Now how do I find that piece of source code in the repository? Let's limit scope to SVN for simplicity - I suspect that using any other source control system will not make much difference in this aspect (correct me if I'm wrong).

If I delete that code and commit the changes it will no longer be in the latest revision. How do I find it without exporting each revision and searching thoroughly (which is nearly impossible)?
