The problem was that the submatch highlight was light magenta on > dark magenta, which I just didn't see. Maybe the colours used for > isearch-group-1 on a 16 colour terminal are suboptimal. They certainly > don't work well on my Linux virtual tty. I think on low-color-number TTYs the colors for all the subgroups should be identical, thus effectively disabling the feature. We don't have enough colors to show the differences on such terminals.
