[mkgmap-dev] Commit: r1432: Add mkgmap: prefix to carpool tag.

Version 1432 was commited by markb on 2009-12-10 17:31:43 +0000 (Thu, 10 Dec 2009) Add mkgmap: prefix to carpool tag. This makes it consistent with mkgmap:unpaved and mkgmap:ferry. The toll tag is now the odd-one-out but as toll=yes is often found on highways, it's probably OK not prefixing it.
