Syntax highlighting for pull request diffs

Hi, I'd just like to submit the idea of adding syntax highlighting for pull request diffs.
This would greatly improve their readability as a lot of people tend to use it for code review. I'm aware of the View file option but it can be impractical when large files are involved.

Visually, I believe it's possible to keep green/red background while still applying coloring in the foreground.

If I remember correctly, Atlassian Crucible has such as feature.
