Re: No longer accessible host paths

[JD Smith]

And one more little bug: if you try to change host but timeout, `file-remote-p` 
no longer things of the file as remote, even though it is `tramp-tramp-file-p`. 
 Then the following:

                      (regexp-quote (file-remote-p source nil t))))

throws an error, since `file-remote-p` is nil.
