There is general agreement on this feature. So I've pushed a patch to the
master branch:

- Add key binding 'C-x x @' to tramp-revert-buffer-with-sudo.
- New command tramp-dired-find-file-with-sudo, bound to '@' in Dired.
- Add handling of prefix argument 'C-u' for both commands, asking
  interactively for another Tramp method but "sudo".

I haven't changed the command names; it doesn't seem to be urgent now we
have the bindings.

Closing the bug.

Best regards, Michael.
