Hi Eli,

The message actually starts as 'Estimating ... NNN' with NNN going up.
Then it changes to 'Estimate PPP/QQQ'. As you rightly noted, this
is not the number of revisions but is an estimate of the number
of records to be fetched. Records can be deltas, full texts, etc.

As bzr uses a streaming protocol to talk to the server, it doesn't
know up front how many records to expect. So there is an initial step
of estimating followed by the progress indication against the
estimate.
