You also need to remove the bit about using %pF or %pf below this

                                        if ($bad_specifier =~ /p[Ff]/) {
                                                $ext_type = "Deprecated";
                                                $use = " - use %pS instead";
                                                $use =~ s/pS/ps/ if 
($bad_specifier =~ /pf/);
                                        }
