* postfix stuff had been applied in wrong order (e.g. int a[2][3] generated
int [addressable][toplevel] a[3][2])
* after fixing that, we've no need for recursion anymore, a bunch of arguments
go away and turn into local variables and we get an easy way to get rid of
bogus space in the show_typename() result.
