I have added an additional check in Tramp for host name matches in such
cases. This checks also the single hop case "/sudo:example.com:", which
shall fail when "example.com" is not your local host name.

There's a new test case for this, tramp-test03-file-name-host-rules. I
have the feeling that this test needs too much time; maybe I'll move it
to the expensive tests.

Could you pls check, whether Tramp behaves now as expected?

Best regards, Michael.
