+              pamtopng: Fix rejection of all BLACKANDWHITE_ALPHA images with
+              message about wrong depth.  Always broken (pamtopng was new in
+              Netpbm 10.71 (June 2015)).  Thanks Karol Kosek
+              <krkk@krkk.ct8.pl>.

+              less than 255.  Always broken (pamtopng was new in Netpbm 10.71
+              (June 2015)).  Thanks Karol Kosek <krkk@krkk.ct8.pl>.

+              (June 2015)).

+              Netpbm 10.71 (June 2015)).
