       self-documentation.
 
 For C:
-    - Follow the GNU coding style:

+    - Follow the same coding style as GtkSourceView:

     - No maximum line length (but short lines are better).
-    - Only /* ... */ comments (for C89 compatibility).
     - Spacing differences with Vala:
        - if (!foo)
        - for (int i = 0; i < max; i++)
