Git commit b99b1a027b6b3a5e0704d17c6357e20de8e918d8 by Kai Uwe Broulik.
Committed on 17/08/2026 at 14:09.
Pushed by broulik into branch 'master'.

In addition to "This key is not known by any other names" also handle
"This host key is known by the following other names/addresses" by
making the rationale part of the regular expression generic.
