Previously, if a reflog entry's old or new SHA-1 was not resolvable
to an object, that SHA-1 was silently ignored. Instead, report such
cases as errors.

I like the idea, but I am a bit uncertain whether it would constitute
"too backwards-incompatible" a change to make this an error. I think
it could be argued both ways: it *is* an improvement, but it could
also possibly disrupt scripts that work pretty nicely at the moment.

What kind of script are you worried about? One that mucks around inside
the object database / reflog files? If people do that, all bets are off,
no? Plus,

* This change only causes fsck to output an extra line (and exit with
  a a non-zero retcode).

* Repair is only a

      git reflog expire --expire-unreachable=now --all

  away, I think.
