[mkgmap-dev] [Patch v1] improve mdr7 index

Wed Apr 12 18:13:32 BST 2017

I have the following rule in my lines file:
highway=track {name '${ref} ${name}' | '${ref}' | '${name}' | 
'${tracktype}'  }
If I got that right, using --x-mdr7-del=Grade1 should avoid all tracks 
tagged tracktype=grade1 (without name and ref) to be indexed, but I can 
still search for them. I tried with and without --x-split-name-index 
without success.
