Thanks; apparently our mails crossed...

I suspect that in a sane repository with set of reasonably packed objects, we can cheaply get a rough estimate of the number of objects to about an order of magnitude (e.g. "likely to have 10k to 100k objects"), and we might able to come up with a way to automatically raise the default length.
