Lists in wikitext are a pain. Proof: number of duplicates of

terminate the list item until the tag is terminated":

Does someone disagree? How hard is it to implement? (Probably rather or
very hard, but who knows.)
For more general context of how I was brought to this problem, and to
discuss alternative solutions for my specific issue, please refer to
