Diff - Add indication of new lines at end of file

When you modify a file in git and add a new line to the end of the file, Git gives you a useful indication that this was the change that was made.

-});
\ No newline at end of file
+});

This is very useful context in a pull request, as you (probably) want to ensure that all changes don't remove new lines from the end of file, which is a gold standard for source files.

So, would be nice if this context was visible in PRs so you don't need to go check the branch out and inspect the file to confirm.
