Oh, I agree, but basically, as a result I'm going to put this patch on
hold until we do a bit more testing.  I'm just not ready to push this
out on the maint branch just yet.....

(The general rule is that I want to keep the maint branch in a state
where someone who wants to take a snapshot for a production
environment should feel generally comfortable to do this --- modulo
rollout/integration testing, of course.  I'll keep it on an
es/fsck-int-node-fixup branch to make sure we don't lose it, but it's
something where I want to add some additional testing before I'm
comfortable rolling it out to the maint branch, just to make sure it
doesn't trigger any regression.)

BTW, while I was experimenting with test cases I found another related
bug (but not a regression) where e2fsck isn't able to fix up a
specific fs corruption (see attached).  It's unlikely to happen in
real life, but given how easily I was able to create something that
e2fsck can't fix, it's clear we were missing some synthetic test
cases.
