I ran through all the issues from sashiko-gemini (sashiko-nipa only reported low
severity issues).

Most of them are false-positives, some are pre-existing and some are purely
theoretical. I have experimented a little with fixing some of the theoretical,
but subsequent local sashiko runs seem to just find new ones indefinitely ;)

IMHO, like Paolo commented on v3, I think these can safely be postponed to
future follow-ups, if need be.

Let me know what you think.
