The reason for not indenting large bodies of code is that when the namespace spans so much, the indent loses any structural value, and turns into just a cost of losing valuable horizontal space in which to write code. This makes sense to me.

> So, I suggest no indent of namespaces ever. I'm happy to make the corresponding change to the coding standards. Naturally, I'm not suggesting rampant re-indenting of code. I'd just like to set a consistent rule going forward so we don't debate this, and know what to do when I see a chunk of code and about to make very significant changes to it and want to clean up formatting while I'm there.

+1 from me.
