 "git fsck" has been taught to report mismatch between expected and
 actual types of an object better.

 Will merge to 'next'?

I think it's ready, also noted last time around[1]. You had one question
on the v10, which I hope I answered to your satisfaction at[2].

Note that Jeff's just-submitted cat-file series[3] will conflict with
this, as they both adjust the same "garbage" object tests. The semantic
conflict is minimal/none, but the textual one is probably annoying
(e.g. his 1/5 uses a variable I split/renamed).

Jeff: Depending on what Junio thinks of queuing ab/fsck-unexpected-type
for next what do you think about rebasing your series on top, or perhaps
take a look at the v10[4] of it/ack it in case that helps with that (since
you've been looking at some related code just now...).
