Martin von Zweigbergk 00d2d2d4fc cli: indicate empty files in default diff format
Empty files can be confusing in diff output. For example:


```
Added regular file file1:
Added regular file file2:
        1: foo
```

This commit adds an "(empty)" placeholder instead. Since it's not
colored, and doesn't have line numbers, it will hopefully not be
mistaken for a file with the contents "(empty)".
