Yes, this is a more general name.  I pushed to master.

BTW, I had a hard time finding the info about one of the most demanding
Tramp features - an ability to edit files with sudo on a remote server.

I searched for "ssh+sudo" by analogy with the git+ssh:// scheme,
but failed to find anything related among all documented methods in
the Tramp manual, even when searched separately for "ssh" and "sudo".
Eventually I found it in an unexpected chapter "Ad-hoc multi-hops"
that allows to do: C-x C-f /ssh:user@host|sudo::/path <RET>

Would it be possible to make this feature more prominent?
