ranges:dates: a point on a connection of its own; --missing still dates every group

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.
