From: Scott Worley Date: Tue, 29 Nov 2011 15:31:20 +0000 (-0800) Subject: Don't use 0 for uninitialized indexes X-Git-Url: http://git.scottworley.com/planeteer/commitdiff_plain/fb8eccbfa74c0ac19f24d40cbc3b7e660eda9eeb?hp=fb8eccbfa74c0ac19f24d40cbc3b7e660eda9eeb Don't use 0 for uninitialized indexes 0 is a valid index. It can legitimately be the head of the optimal path. When it was the head of the optimal path, DescribePath() would print nothing. This fixes that bug. ---
