Sorry, but the "bug" is that someone doesn't know well the language's syntax and/or has spent too much time with braceless languages and tries to put as less braces as possible because of their personal preferences, resulting in a wrong block structure. Maybe I'm just different than you, but I immediately notice the missing braces. Actually, the visual cues I look for (even when skimming the code) are the braces, not the indentation; especially, the missing closing brace at the end of the block alerts me. The indentation is a plus, an added redundancy. Moral of the story: not everyone reads code the same way.
