You don't think changes should be reviewed (that's what I said above, I did not necessarily say it should be reverted)? That's way out in left field if that is what you really think. As for reverting the changes, I think they are small enough that is probably a bit overboard unless someone else reports an actual problem with them. (Specifically, I don't think the bar is high enough in this case to warrant a reversion.) However, I think that for future changes, Dimitry should get these sort of changes reviewed before committing them. -- John Baldwin
