Oops, thanks for catching that - I'll fix it.

That's OK.  It turns out that fetch_alternates() function itself
is now called from the main just once; it used to be called
lazily and needed the call-once guard.

I'd thought about chaining the alternates, but wasn't sure whether it's
safe to consider all alternates in the chain equivalent.

Well, I decided we shouldn't, because the original repository
that has objects/info/alternates surely doesn't.
