I'm struggling to understand under which conditions this adds/changes
entries in ~/.ssh/known_hosts.

So far it always fails with "wildcard known hosts name found,
skipping UserKnownHostsFile update".

I don't have any wildcard entries in known_hosts.  I _do_ have a
number of entries with multiple addresses like this:

  partoc,fddd:28ee:243::4,172.16.0.4

So it skips those.  But it also skips very basic entries like

  amd64.ports.openbsd.org,199.185.231.80
