zsh 开启 autosuggestions 插件的时候，在终端中的黏贴操作变的非常慢，在 .zshrc 配置里加入下面的代码可以修复这个问题

# This speeds up pasting w/ autosuggest
# https://github.com/zsh-users/zsh-autosuggestions/issues/238
pasteinit() {
  OLD_SELF_INSERT=${${(s.:.)widgets[self-insert]}[2,3]}
  zle -N self-insert url-quote-magic # I wonder if you'd need .url-quote-magic?
}
pastefinish() {
  zle -N self-insert $OLD_SELF_INSERT
}
zstyle :bracketed-paste-magic paste-init pasteinit
zstyle :bracketed-paste-magic paste-finish pastefinish
