SSHFS interprets symbolic links on the local host. An absolute file name cannot work, therefore. I've added ("-o" "transform_symlinks") to the tramp-mount-args of the sshfs Tramp method. This shall fix it. Pls unmount any sshfs mounts prior testing, otherwise it wouldn't work. An alternative would be to use ("-o" "follow_symlinks"). But this has the disadvantage that symbolic links look like regular files then, so I haven't used it. Pushed to the repositories. You'll find it on the master branch, and in the upcoming GNU ELPA Tramp 2.5.2.2. Closing the bug. Best regards, Michael.
