    Ensure fgets read at least one byte before modifying string
    
    If a file has a \0 byte (binary file, strange encoding, corruption),
    fgets() can return a string starting with a \0 byte - check for that
    before checking to see if the byte before the \0 is a \n, so we don't
    reach back before the start of our memory buffer.
    
    Also check that the penultimate byte is a \n before we chop it off,
    in case we're reading from a file missing a newline, or a line longer
    than fit in the buffer provided to fgets().
