As I already said, this was the culprit.

But now I've seen that I already had an emacs specific setting in my
~/.zshrc which I added to make M-x shell work.

--8<---------------cut here---------------start------------->8---
if [[ -n ${INSIDE_EMACS} ]]; then
    prompt gentoo
    unsetopt zle
fi
--8<---------------cut here---------------end--------------->8---

So it would be good, if TRAMP would set this INSIDE_EMACS variable, too,
in analogy with M-x shell.

In M-x shell, its value is "23.0.60.1,comint" here.  It would be nice if
TRAMP would set it to something like "<emacs-version>,comint,tramp", so
that users have a mode finegrained control of what's invoking the shell.
