This is the standard way of splitting the output of a command into
lines and dropping empty lines:

  list=( ${(f)"$(setopt)"} )

This requires KSH_OPTION_PRINT, just like your code. It may not be the
best idea to write code that deals with options in a way that requires
specific options.

It's unlikely that you need to capture the output of setopt in the
first place given that there is $options associative array.

  () {
    local k v
    local -A color=(on 32 off 33)
    for k v in ${(kv)options}; do
      printf '%-20s = \e[%sm%s\e[0m\n' $k ${color[$v]} $v
    done
  }

Dealing with options as an associative array is a lot easier than
dealing with text.
