Unfortunately there's no newer upstream release and this bug is present
in the ncurses 5.9 version in Fedora 20 as well. From what I gather from the
surrounding code, I *assume* something like this could fix it
 case 'i':
 y = npop();
 x = npop();
 if (p_is_s[0] == 0)
 y++;
 if (p_is_s[1] == 0)
 x++;
 npush(x);
 npush(y);
 break;
I'm not sure the relation between x, y, and the p_is_s indices is
correct, though.
