Subject: 24.4; Cannot jump to bookmark with tramp-via-proxy

I'm using tramp with sshx & sudo for logging into remote machines as a
normal user and editing root-owned files there. I have some files that I
visit often, so I set a bookmark to these files. When I jump to such a
bookmark I receive the following error message:

--------------------------------------------------
Tramp: Opening connection for root <at> spector using sudo...failed
byte-code: Host `spector' looks like a remote host, `sudo' can only use the local host
--------------------------------------------------

How to reproduce:

1. Run `emacs -Q`

2. Connect to a remote host via a proxy,
e.g. "/sshx:mbunkus <at> spector|sudo:root <at> spector:/var/cache/bind/domain.db"

3. Set a bookmark with M-x bookmark-set

4. Save the bookmarks with M-x bookmark-save

Here's how such a bookmark looks like:

("domain.db"
 (filename . "/sshx:mbunkus <at> spector|sudo:root <at> spector:/var/cache/bind/linet/domain.db")
 (front-context-string . "; -*- mode: zone")
 (rear-context-string)
 (position . 1))

5. Exit and restart Emacs with `emacs -Q`

6. Jump to the bookmark set in 3.; now the error message occurs.

What's interesting is that I circumvent that error by manually opening a
similar tramp-sudo-via-sshx-proxy connection to any file on the same
host (e.g. to
"/sshx:mbunkus <at> spector|sudo:root <at> spector:/root/.bashrc"). After I've
done that once jumping to the bookmark miraculously starts working (no
further errors, the files are opened just as I expect them to
be). However, bookmarks to other hosts do not start working after such a
workaround.

Thanks for confirmation. I've committed the patch to the emacs-24 bzr
branch; shall arrive your git checkout within a few days.

Closing the bug.
