Comment 11 for bug 1508169

Hi Kyle,
I have implemented this patch. At the same time I got answer from OSM(OpenStreetMap), they suggested we use Open Cage API(http://geocoder.opencagedata.com/api.html#formatte) which uses the same database of OSM but the address is formatted.
Below is a comparison between the two solutions. IMHO, Open Cage works well.
the value of address is got from OSM which is the basis for me to format.
the value of display_name is used by current solution, also from OSM.
the value of formated_name is the result after I adapted address according to LC_ADDRESS.
the value of opencage is I got by using Open Cage API.
