some comment clean ups

I use codespell
http://www.exactmagic.com/products/codespell/
$29 USD

It has a few minor bugs in the release version
but it has an auto update feature that u can use to update to the latest beta.

I also recommend against running it on all files for a large solution. It is fairly CPU intensive. Better to go project by project.

Full fixed on trunk; partial on 2.0.x branch.
Thanks again but please let me know what you are using...

Excellent work but please let me know what you are using... I can't believe that you read all comments.
