unexpected soft update inconsistency - cannot fix

[Julian H. Stacey]

Hi Kirk cc fs@, 

OK, it all worked as you said, Thanks for the explanations ! 
Maybe if I or others get some time it'd be worth tweaking the code:
- It's suprising ".." has to be 2nd entry & fsck/fsdb can't find it later.
- fsck &/or fsdb dont have to just give up on no parent inode,
  they could search down from root looking for a prent inode listing
  the damaged child inode, like I did with find, (Possibly first
  stab might be some nasty system("...") cludges to a printf as a
  hint to user).
I'll save this mail thread in my personal tree in case 
I get time to hack code :-)
