Regarding extra spaces and tabs. I think some of this happens from editors. I use emacs and recent changes do auto-indent which I manually unset in a .config file. Also, sometimes when folks play around with continuation lines, you can sometimes end up with extra spaces at the end of a line. It's not a big deal and I'll periodically do a clean. I have a sed script now so it takes like 2 seconds to clean up.
