Currently, one of the hardest diffs to review, is when a bunch of code gets indented positively or negatively. It's hard to tell if the user actually made a change somewhere in the indent code because it all mostly looks the same.

Here is prime example: https://gist.github.com/blainekasten/cfd44975df7c294c54e6/revisions

Hardly any code was changed, just de-indented.

It would help if we could see the actual code that changed, and then indent changes were hidden and noted. Something that looked more like this:

- removedThisFunction(function() {
+  de-indented containing content 2 spaces
- });
