[mkgmap-dev] [PATCH] better used tags handling in rules

Hi everybody, I intend to commit this sometime soon (in a week, maybe earlier), so I'm looking for some comments or even testing. Issue: If you have a style A that has a base style B, only the main tags from A are considered. This means, that many rules from B are not used. I haven't tracked down exactly why and where it happens, but I assume, that some code cleans up the osm data straight after/while reading it and removes any "useless" tags. To save memory. Anyway, I found a solution: Update the "usedTags" of the RuleSet after merging in the base-RuleSet. The patch is simple, I think. Elrond
