bug#50186: Shell in emacs very annoying using zsh

[Eduardo Ochs]

Zsh is one of the programs that I need to run with
`comint-process-echoes' set to t in the comint buffer...

?ηÉ/orbitingflea, can you define these two functions,

  (defun det () (interactive) (setq comint-process-echoes t))
  (defun den () (interactive) (setq comint-process-echoes nil))

and then use Zsh a bit with comint-process-echoes set to true and a
bit with comint-process-echoes set to nil - use `M-x det' and `M-x
den' to change the value - to see if something changes?

Wow! That's surprising to me.

Maybe I should show my zsh config file that generating this bug:

export ZSH="/home/friend/.oh-my-zsh"

ZSH_THEME="ys"

plugins=(git)

source $ZSH/oh-my-zsh.sh

export DISPLAY=`cat /etc/resolv.conf | grep nameserver | awk '{print $2}'`:0.0

export PATH="/home/friend/.local/bin:$PATH"

Here I used "ys" theme of oh-my-zsh, and it has multi-line prompt.

By the way, I tested bash with multi-line prompt, as you said. No problem.

So the problem comes from zsh?
