What is the current behavior?

8 of the relative URLs must start with "/" tests in tests/content/lint-files.js fail because of some windows pathing issues. Here is one example.

What changes are you suggesting?

The problem is with the relative path computations near the beginning of the test. These should be wrapped with a slash call.
