I think this comment (and the similar one below) is probably unnecessary, and
could be omitted.

+        files = {'/file': 'e\x87[P',
+                 '/mock-checkout/third_party/WebKit/Source/core/css/CSSProperties.in': '', }

+        convert_for_webkit('', '/file', '', host)

Optionally, you could add a comment that this test passes if no Exception is
raised.
