I noticed that this was sometimes printing an aka that was exactly the 
same, which looks a bit goofy.  So this patch makes sure that the 
typedef-stripped version actually prints out differently before 
appending the {aka}.

Tested x86_64-pc-linux-gnu.  Gaby: I'm not entirely comfortable messing 
directly with the obstack here, but the pp interface doesn't seem to 
support multiple strings at once.  Does this approach make sense to you, 
or do you have a better idea?
