I think reftables are still a while off, and even once they are here, many people will still be using the older format. So it makes sense to still apply fixes to the old code. What I wonder, though, is whether always refreshing will cause a noticeable performance impact (and that's why I was so slow in responding -- I had hoped to try to come up with some numbers, but I just hadn't gotten around to it). My gut says it's _probably_ not an issue, but it would be nice to have some data to back it up. > **And thank a lot for your reply, it's great to me, because it's my first > PATCh to git myself :)** You're welcome. Thanks for diagnosing a rather tricky case. :) -Peff
