Hi,

I've spotted a problem with TRAMP when using multi-hop ssh with
find-file-visit-truename set to t.

Assuming that there is a remote machine XXX.YYY.com with SSH server. On local
machine I run emacs like that:

> emacs -Q --eval '(progn \
>       (require (quote tramp)) \
>       (setq find-file-visit-truename t) \
>       (with-current-buffer (find-file "/ssh:root@XXX.YYYY.com|ssh:localhost:") \
>       (tramp-cleanup-all-connections) \
>       (revert-buffer)))'

It successfully connects to the remote machine and opens dired buffer with the
correct content, but the filename name in the dired header is not
'/ssh:XXX.YYYY.com|ssh:localhost:' as I might expect, but
'/ssh:localhost:/root:'. After (revert-buffer) I get an error in *Messages*:

> tramp-handle-access-file: Reading directory: No such file or directory /ssh:localhost:/root/

The issue does not reproduce if find-file-visit-truename set to nil. It looks like 'file-truename' doesn't work correctly with multi-hop tramp file names.
