Tramp opens a local shell, the prompt is "$ ". OK.

Tramp applies the ssh command to the remote host. The prompt is "# ". That
is OK; tramp-shell-prompt-pattern covers this.

Tramp starts /bin/sh on the remote host, and expects "$ " as prompt (see
PS1). But the prompt is still "# ". That is NOT OK.

Is there something in the .profile of root, which overrides the PS1 settings?
What happens, if you manually apply "ssh harry -l root -q -e none" and
then, afterwards, "exec env ENV='' PROMPT_COMMAND='' PS1=\$\ PS2='' PS3='' 
/bin/sh"?
