Sixteen groups never got through on one connection (a reply timed out
after 2 minutes); now a timed-out point is skipped and logged, the
group goes on, and stops after 3 failures. estimate() ignored --missing's
filter: it dated 0 groups on the second run.

ranges:dates samples each active group's posting dates from the news
server (group_dates) and estimates every range's date (ranges.est_date).
ranges:capture --from --to marks a window's ranges of every group for the
corpus. The corpus fill takes capture ranges in priority order, done ones
too, and remembers complete ones (ranges.stored_at).
