This is new since the RFC series, but I'm not sure I understand.  Is
the issue you're fixing here that a 'git init somerepo' would hit this
codepath and print funny errors because HEAD doesn't exist yet and
thus the whole `git read-tree -mu HEAD` stuff can't work?  Or that
when the remote has HEAD pointing at a bad commit that you get error
messages different than expected?
