trac delete-user script misses spam comments sometimes
Our delete-user script, for cleaning up after spammy users, seems to miss comments sometime. For example, I ran it on the user that spammed #12336 (closed), and the script was happy and said it had deleted everything, but the spam comment remained.
Maybe the @ in the user name confused it?
