[mkgmap-dev] Commit: r2169: When building mdr20 take account of the map number and the city

Version 2169 was commited by steve on 2012-01-15 22:36:15 +0000 (Sun, 15 Jan 2012) When building mdr20 take account of the map number and the city when deciding if a street is the same or not. Also set again a flag that was accidentally not set after the change to add gmapsupp indexes in mdr5.
