I like this idea. But I don't think the default should be -1, since
that significantly changes the current behavior, and makes certain
tarballs get out of date perpetually, like downloading a zip of HEAD
or what happens when history is rewritten.

Currently it defaults to cache_repo_ttl, which is 5. I'd be willing to
compromise for 15 if you prefer.
