[mkgmap-dev] Commit: r1435: Avoid assertion when splitting way at a previous node.

Version 1435 was commited by markb on 2009-12-11 22:07:43 +0000 (Fri, 11 Dec 2009) Avoid assertion when splitting way at a previous node. When a way is split to avoid exceeding the maximum number of points in a way and the split is done at a previous node, set a flag so that the later code that checks for duplicate node indices doesn't barf because the node index has already been seen before. In fact, in this situation, we can reverse the check such that it requires the node index to have been seen before and it will barf if it hasn't.
