I noticed while scanning #git log that it appears that pack-refs
was run in your public repo and some people cannot clone over
dumb protocols with older git.

    git-fetch: fix dumb protocol transport to fetch from pack-pruned ref

was the first revision that aligned dumb protocol clients with
pack-ref; unfortunately anything older will not find the ref
that was packed.

We do have a backward compatibility warning on this in v1.5.0
release notes draft, but I think we would make it more obvious.

Sigh...
