[mkgmap-dev] addr:street and street name matching for house number searchs

Mon Aug 17 16:12:16 BST 2015

Your patch caught 19293 lines of my log. Although those cases must also 
be corrected in OSM data, they can now be put in a second priority 
level, so +1 from me to commit the patch.
Have you thought about including alt_name in the match search when 
matching with name fails? I have found some cases where it can help.
