TruncatedReply: a compressed reply the server cut at a ".\r\n" fails in 2 s; ranges:dates samples plain

Eweka stops a compressed XOVER reply at the first ".\r\n" in its own
output (78 01 2e 0d 0a and nothing more), which some small replies begin
with; the text path waited for more until the reply timeout. ranges:dates
uses plain connections of its own instead of the pool.
