Tracing Sieve actions

I encountered an interesting problem that one originator was being dumped into the Deleted file directly by my sieve. The sieve file was quite large and it was not obvious which entry was causing the issue. I recall there was a way to get sieve-test to show what is going on and which lines it used, but I could not replicate it tonight for anything. I ended up having to change all the deliver to the Deleted files to something else and test one at a time to find the offending entry. It took a long time. How do you get sieve-test to show the actual path it took through the file?
