During the review of the first iteration of the patch series to remove sections that become empty upon --unset or --unset-all, Jeff King identified a couple of problematic cases with the backtracking approach that was still used then to "look backwards for the section header": https://public-inbox.org/git/20180329213229.GG2939@xxxxxxxxxxxxxxxxxxxxx/ This patch adds a couple of concocted examples designed to fool a backtracking parser.
