I would have thought that receive.fsckObjects would reject it, but seems
that git-fsck does not complain about it at all, as it is otherwise
syntactically valid (a space separating the zero-length name from the
email, and <> surrounding the empty email).

We do complain during "git commit" about an empty name. We don't seem to
do so for blank emails, though. The only discussion I could find
mentions that should probably disallow both[1].

I wonder how this commit was created in the first place (through
git-commit, and we have an empty-name case that is not covered, or using
a lower-level tool that bypasses the checks).
