do you have a public git clone?
iam asking because merging changes from there should be easier than
applying quoted and line broken patches

about the patch itself, have you tried just injecting cur again at
EOF ? This should avoid special casing things as there would be just
2 references to the same pic instead of a missing pic

thanks
