[mkgmap-dev] Splitter default description with comments (patch)

Hi list, As discussed before, I think it's a bit confusing that Splitter has a default "description" in it's template.args file that says "OSM Map". The attached patch fixes this: it puts "#" before the description if you didn't specify a --description. This also helps --description in mkgmap, as it will work as advertised, without hidden settings elsewhere. This is the patch for Splitter, cleaned up (there was a spurious comment in an unrelated file in the previous one). Best regards, Valentijn
