Does anyone know how the "rv" tag on the Finnish Wiki works. There are several types of reverts including one whose edit summary begins with "Hylättiin viimeisin ..." but is not tagged as either an undo (Kumottu) nor a rollback (Palautettu takaisinpäin). This would complicate matters further when I notice here that every rollback in article space now has three tags, while those in other namespaces lack the "rv" tag but has the other two.
