I didn't write clearly when I said "Lmode only has positive values of 1-4, with 0 being none", I meant to say more like "The positive values in Lmode should be not go higher than 4".
I still haven't quite figured out how those 18 different "repair" modes are supposed to work within the context of the filter. I think they're supposed to be different degrees of grain removal (-18 being the most grain removed).
I also know it's not very good form to mix up different scripts / different versions of things in one bug report post, but I couldn't help but do some comparisons because I'm not sure in some cases which is supposed to be like the other.
