This is Colin O'Flynn's mega patch for updating safemode support:

Browse Source 
* add support for parts with just 'fuse' memory

    * if any fuse memories are altered, reflect those changes in the
      post-programming safemode check so that safemode no longer
      complains about fuses which were intentionally altered; this
      eliminates the need to completely disable safemode using -u in
      order to program fuses.

    * provide -s option which will not ask to restore fuses, it will
      just do it
