Odd ^[[2004h characters with shell and ZSH

[darkfeline]

The new 5.1.1 release of ZSH adds support for bracketed paste. This results in the odd effect of printing the bracketed paste control sequences ^[[2004h and ^[[2004l when running ZSH in shell mode.

I believe comint already supports the necessary escaping and pasting, so bracketed paste is redundant.

Workaround is to disable bracketed paste when inside Emacs, by adding the following to .zshrc:

if [ -n "$INSIDE_EMACS" ]; then
    export EDITOR=emacsclient
    unset zle_bracketed_paste  # This line
fi

This is sort of an upstream bug since ZSH shouldn't be attempting bracketed paste on TERM=dumb, but oh well.

So, what do we do here?

Forgot to close. I don't think there's anything for Spacemacs to do here unless there are more misbehaving programs that do this on TERM=dumb. I meant to document this in case anyone else ran into it.

Ah, no problem. 👍

Thanks for mentioning this despite it being an upstream bug. I've been trying to fix this for weeks!
