Comment (by blair@…):

 Patches welcome.  Also, pylint typically has updated requirements on its
 dependent ports, py*-logilab-common and py*-logilab-astng, so those might
 need updates also.  I don't have the cycles to do the work now, but if you
 put some patches together that I could test and just commit, that would
 help a lot.
