I mis-spoke. It was with 2.2.2. Does it not happen for you?

Postponing makes sense. when it lists something like 0 .. 112 is it
having to make 112 network calls? If so, then each network call is
taking something like 1/30th of a second (30 ms) which I guess sounds

I wonder if it really needs to descend to that level. Maybe it could
stop one level above that, unless --detail was specified. Or, if you
really feel it can be optimized away almost entirely, at some point,
without too much pain, it's probably not worth doing anything with it yet.

operations someone might try is browsing a remote archive such as the
ArX tree.
