[mkgmap-dev] [patch] add ability to have unlimited ValueFilter chains

Hi, Here's a patch to add ability to have unlimited ValueFilter chains. I'm using this with the SubstitutionFilter to normalize the road types with a rule like this: highway=* { name '${name|subst: Street=> St|subst: Avenue=> Ave|subst: Road=> Rd}' } Any thoughts on this? I'd be happy to hear about a better way to accomplish the same task if this isn't good. Thanks, Ben
