Yes, I do anonymize them (and check it in the tests). See
anonymize_refname. I just forgot to include it in the list. Trivial
squashable patch is below.
The few things I don't anonymize are:
1. ref prefixes. We see the same distribution of refs/heads vs
refs/tags, etc.
2. refs/heads/master is left untouched, for convenience (and because
it's not really a secret). The implementation is lazy, though, and
would leave "refs/heads/master-supersecret", as well. I can tighten
that if we really want to be careful.
3. gitlinks are left untouched, since sha1s cannot be reversed. This
could leak some information (if your private repo points to a
public, I can find out you have it as submodule). I doubt it
matters, but we can also scramble the sha1s.
