Which at least said in the description the unrelated things it was 
doing.

I thnk the above should be an ERROR and cause failure without
the -f (force) option.

The total_size says how much data should be copied.  Anything
less and there is data missing.   Assuming zeros is wrong for
most sections (the exception being the memory reserve list
that had a terminating 0 entry within the read portion).
