Remove goto L12 - take two

Remove goto L12 - take two

On't know if you let me near this code again but here is a second
stab at removing "goto L12"

Previous attempt failed because of trying to continue the outer
do{}while(false)
Adding an extra for(;;) loop where the only repeat is the former
"goto L12" is replaced by continue. All other exits are returns
and a break;
