    vm_page: Fix loading bad memory addresses from file
    
    When loading bad memory addresses from a file, we are passed an end
    pointer that points on the first byte after the buffer. We want the
    buffer to be null-terminated (by changing the last byte to \0 if it is
    reasonable to do so), so adjust the end pointer to be on that byte.
