t4214: demonstrate octopus graph coloring failure
The graph coloring logic for octopus merges currently has a bug. This can be seen git.git with 74c7cfa875 (Merge of http://members.cox.net/junkio/git-jc.git, 2005-05-05), whose second child is 211232bae6 (Octopus merge of the following five patches., 2005-05-05). If one runs git log --graph 74c7cfa875 one can see that the octopus merge is colored incorrectly. In particular, the horizontal dashes are off by one color. Each horizontal dash should be the color of the line to their bottom-right. Instead, they are currently the color of the line to their bottom. Demonstrate this breakage with a few sets of test cases. These test cases should show not only simple cases of the bug occuring but trickier situations that may not be handled properly in any attempt to fix the bug. While we're at it, include a passing test case as a canary in case an attempt to fix the bug breaks existing operation.
