Harlington. Middlesex, England

region GB 51.486, -0.436

Left the name as recorded (stray period) rather than renaming to 'Harlington, Middlesex, England' — that exact string already exists as #6567, which is mis-geocoded to Harlington, BEDFORDSHIRE (Q975042). Do not merge into #6567 or its twin #3729 'Harlington, England' (same wrong coords) until those are fixed to Q2344963/51.4859,-0.4364 in a follow-up pass.
