I don't think this is needed since you're already adding it to TEST_ALWAYS_FLAGS. The tests pass without this for me.

+ int max_width = 80, right_margin = 10;

Let's not hardcode these numbers. We should use getenv("COLUMNS") for the width if it's set; otherwise I would lean toward unlimited width. And I'm not sure why we need a right margin at all.

+  s = expand_location(diagnostic->location);
+  line = location_get_source_line (s);

Why not expand the location inside location_get_source_line?
