Thanks. I've made a further improvement in tramp-file-local-name. In
case NAME is not a Tramp file name, it calls file-local-name now.

This is to handle use cases like

(copy-file "/ssh:host:/path/index.html" "https://example.com/path/index.html";)

and more subtle constellations.

You can change this now to

(setq files (mapcar #'tramp-file-local-name files))

Best regards, Michael.
