Steps to reproduce:
- Be a sysop.
- Find a revdel'd revision which also triggered some filter(s) (eg. a tagged one).
- Try to find an AbuseLog entry for the edit.
If you don't have abusefilter-hidden-log right, you won't succeed. I think this doesn't make sense (unless the entry is hidden as well, otherwise you need special rights). If I can see the text that was hidden, why cannot I see the log entry, which reveals nothing I don't know?
Giving live examples would be pointless because logs are usually hidden from ordinary users.
