Wait a minute.  How did "git fetch http://host/repo.git" work before C
rewrite?

The reason I ask is because info/refs traditionally did not list HEAD and
fetch either would have failed to start walking from HEAD (iow, the issue
was very old), or it didn't care (iow, the issue is a regression after C
rewrite).
