This is correct, well investigated!

I'd love to see the example displayed in vimdiff format. Many good looking themes become unusable when vimdiff highlighting is applied.

Seconded. The same thing also applies to folds in vim, and sometimes to gutters and things like NERDTree or ctags scripts. It's really frustrating to have a great theme that in certain edge cases applies black text on a black background or (more commonly) white text on a light gray background.

Can you put the theme permalink in the generated theme files as a comment? Seems like it might be handy to have someday.
