Changes (by Quozl):

  * next_action:  diagnose => code


 The inode reference count error is due ''+link-count'' not checking
 filesystem feature bits.

 The directory count wrong error is due to the bg_used_dirs_count value in
 the group descriptor not being maintained by Open Firmware when a
 directory is created, or deleted.  used-dirs+! is easily implemented, but
 the call to it needs to be placed properly in the $mkdir and $rmdir flow.
