+    Header stats missing with python3
+    
+    Ick! took me a while to find this. Python3 changed division from providing ints
+    to floats. This in turn caused our header panel to call addstr with float x/y
+    coordinates, which made that funciton fail silently. End result is that when
+    the header panel showed two columns of stats the right column was missing.
+    
+    Caught thanks to Stijn.
