mkinit.pl oddities

In v1.1, mkinit.pl on lines 112, 171, and 565, there are statements like:
printf "$s without init: $initdat\n";

$s is never defined locally or globally, as far as I can tell.

In addition, only the data from init.GGGd seems to be used to determine the "average n_good" (@stands only contains GGGd)
