When adding new highlight groups, one needs to make sure to also add a "default link NewHlGroup ExistingHlGroup" in highlight.c code, so that when resetting a color scheme the old color won't be left behind. So add a Makefile in the 'ci' directory that verifies that all documented '*hl-<groupname>' from the documentation are either reflected in the source code, or belong to a list of 'known to be ignored' highlight groups and let that check run as part of the CI test suite. related: #16676 closes: #16678 Signed-off-by: Christ van Willegen <cvwillegen@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
