Look for the string 'gcc-include' in the example.  In description it
claims that the first two lines would be highlighted as information
and the last as error.  In reality, second line:

                 from /usr/include/c++/3.3/backward/iostream.h:31,

is also highlighted as an error because it is handled by 'ruby' rule.

I would also argue that _all three_ lines should be information
because real error follows those, but that is a different issue.
