Simplest ssh line

[積丹尼 Dan Jacobson]

In (info "(tramp) Quick Start Guide")

  If your local host runs an SSH client, and the remote host runs an SSH
  server, the simplest remote file name is ‘/ssh:address@hidden:/path/to/file’.

My experiments found that

/ssh:address@hidden:.

works and is simpler than

/ssh:address@hidden:/home/user

so mention that too. Maybe I don't even need the trailing dot. Mention if/not.

Also if one can do

Anyway, users wonder
"If I can do
$ ssh host
as a shortcut to
$ ssh address@hidden
as I am the same user there,
then maybe some shortcuts are possible when calling tramp too."
So please mention them there!
