bug#30946: 26.0.90; TRAMP cannot access some files when using hops

[Nicolas Petton]

As discussed on the emacs-devel mailing list, when using tramp with
multiple hops like the following:

  C-x C-f /ssh:me@example.com|sudo:localhost:/etc/deluser.conf

Tramp opens an empty buffer, without showing any error message.

I understand now that the second hop should be "sudo:example.com:", but
it felt intuitive to use localhost, and for most files on the remote
host it actually worked.
