I actually did have a real life scenario that was improved, but it's not very typical. As I've mentioned before, we keep a big shared-object repository for forks of a single repo, so a fairly common operation is git -C network.git fetch ../$fork.git +refs/*:refs/remotes/$fork/* The first time that's run on a fork, everything looks like a new ref. So "real life", but thankfully not life for most git users. :) -Peff
