Fix deleted line return

Browse source 
For some reason, `isprint()` claims that `0xff` is printable. But it's used by print functions as a magic value to suppress the line return.
So when viewing a dump where the last byte of a block/sector is `0xff`, it was suppressing the new line between blocks/sectors.
