Feature request: add option for emacsclient to open files in a specific mode

Zsh has a built-in feature that enables users to edit the current
command using $EDITOR. Specifically, Zsh uses the following function:
```
edit-command-line () {
() {
exec < /dev/tty
setopt localoptions nomultibyte noksharrays
(( $+zle_bracketed_paste )) && print -r -n - $zle_bracketed_paste[2]
local editor=${${VISUAL:-${EDITOR:-vi}}}
case $editor in
(*vim*) integer byteoffset=$(( $#PREBUFFER + $#LBUFFER + 1 ))
${=editor} -c "normal! ${byteoffset}go" -- $1 ;;
(*emacs*) local lines=(${(f):-"$PREBUFFER$LBUFFER"})
${=editor} +${#lines}:$((${#lines[-1]} + 1)) $1 ;;
(*) ${=editor} $1 ;;
esac
(( $+zle_bracketed_paste )) && print -r -n - $zle_bracketed_paste[1]
print -Rz - "$(<$1)"
} =(<<<"$PREBUFFER$BUFFER")
zle send-break
}
```
However, emacs will by default open the file in fundamental mode.

It would be neat if one could specify for the case where
EDITOR=emacsclient to open file in shell-script-mode since the syntax
should be compatible.

A current workaround is to add the following to init file:
```
(add-to-list 'auto-mode-alist '("/tmp/zsh.*" . shell-script-mode))
```
since the temporary file created by zsh for editing always will begin
with the name "zsh".
