The thing is that there are probably leftover tabs and spaces and whatnot everywhere. Going hunting for those things won't make anything work better, won't improve knowledge of the codebase for the one who does it and will only be a hassle to verify that they don't introduce - intended or not - bugs due to simple mistakes.

I think the focus should be on improving functionality - which your first patch did and I thank you for it. But if there are _only_ visual enhancements in the source code, those things would be better to handle with proper development tools rather than huge commits.
