bug#1115: 23.0.60; Tramp hangs via 'su' with zsh

[Gour]

Hi!

Few days ago I noticed that after building latest CVS I cannot edit
root's files via usual 'su' mechanism.

At first I thought the problem is that something was broken in the
latest code, but after attempting to build one month old CVS version and
seeing the same problem, I was convinced it's something else.

Then i remembered that recently I changed my root's default shell to zsh
and, indeed, after changing root's default shell to bash Tramp works
again.

Here is the output I got in tramp's buffer after setting 

(setq tramp-debug-buffer t)

(nitai is my local hostname)

Sincerely,
Gour

It looks like the zle problem. Read the Tramp manual about

Yeah, I got some help on zsh and put the following in my .zshrc files:

case $TERM in
    dumb) # tramp
        unsetopt zle
        ;;
esac


and the above solves the problem of accessing the root files on the same
machine via 'su'.

However, the remaining problem is remote access to files (e.g. from
laptop to desktop) when the tramp fails with when the remote machine has
the following 'prompt':

PS1="[%{${fg[green]}%}%n%{${fg[black]}%}@%{${fg[blue]}%}%m
%{${fg[red]}%}%1d%{${fg[black]}%}] "


The tramp's 'trace' is below:

Any idea?

Commenting the above PS1 'solves' the problem.

Tramp is not able to detect such a prompt. Please set $PS1 to "$ " or
something like this, when $TERM is "dumb".
