You can pass git blame -w to ignore whitespace changes, though yes, in general it is annoying.

I wouldn't have made this comment if I knew that. Though I suppose this is still an annoyance for git web interfaces. Thanks for the info!

On GitHub you can add ?w=1 to diff URLs to get the same thing (there's a button for it too?)

I can't find the button. I guess it's a hidden feature
