Sorry about that. My client displays it nicely so I didn't realize it was getting difficult to read. I see your point though. I find [QUOTE] [/QUOTE] mechanism a little difficult to follow with nested comments. I will continue using my current approach, which Ben also recommended, of adding an additional '>' character to previous comments. In addition, I will also trim down the content that is not relevant. Hopefully this will make it easier to see my comments. Let me know if this still doesn't help.

Hm, I was under the impression that this was already a part of the style. Thanks for fixing it anyways.

I strongly prefer/advice not to do such refactoring in a separate review. It wasn't fun reviewing this function at all. I spent way more time reviewing it & at the end I was still not confident about my review. That is why I asked for a refactor. Doing the refactoring now has a lot more context than doing it at a later point. Not to mention this unnecssarily adds more burden to the review effort. We spend good amount of time reviewing a long function call only to review it again when the same logic gets refactor. I see that you have already sent out a separate review for refactoring, so I will take a look. But I really really don't prefer this.

I take back my earlier comment. While I still prefer the more condense form of commenting, I think most of our code does follow the style that your prefer. Presumably because others prefer that style too. So let's keep that going. We should clarify this in the style guide.
PS: Hopefully this reply is easier to follow.
