Need for return code to indicate pass/fail

[Google Code Exporter]

What steps will reproduce the problem?
1. diff 2 identical files
2. diff 2 different files

What is the expected output? What do you see instead?
There is nothing to indicate when a diff has no differences. I would expect
some kind of return code to indicate this.

What version of the product are you using? On what operating system?
v1.0, Ubuntu 9.04

Please provide any additional information below.
