[mkgmap-dev] Exit_hint and Dest_hint result is not what I was expecting

Sat Mar 19 19:51:39 GMT 2016

Why do I get a result string:
*Exit 18 Beck Rd ~ Beck Road *

when the only command line with a ~ is :

line 89
'${destination:street} ~ ${destination}' |

and you can see from the OSM data that (JOSM screen capture pic) that there
is NO DESTINATION tag, but only DESTINATION:STREET tag=Beck Road.

How is my string being formed?

If I could prove that ${destination} contains the string "Beck Road" then
there is something that is copying DESTINATION:STREET into and empty
DESTINATION tag
