Tilde expansion is not possible for sshfs (and adb, rclone) methods of
Tramp. I've added a check, and Tramp raises an error now when it detects
a tilde. Pushed to master.

However, this breaks shell-command for these methods. In shell-mode,
comint-input-ring-file-name is set to something like
"/sshfs:user@host:~/.history". Expanding this file name raises the error
now. I have no idea how to fix this. Setting comint-input-ring-file-name
to "/sshfs:user@host:/dev/null"?

Best regards, Michael.
