However, you're not the first to get burnt by this mis-assumption, so maybe we should do something about it.
The low-tech solution to this would be to stop listing the default values as commented-out entries, but just make them ordinary uncommented entries. That way people who think "undoing my edit will revert the change" would be right.
I would be in favour of that way of doing things. I have always found it weird that defaults were commented out...
