I had _split_shell_arguments_under already:

autoload -U split-shell-arguments

function _split_shell_arguments_under()
{
  local -a reply
  integer REPLY2
  split-shell-arguments
  #have to duplicate some of modify-current-argument to get the word
  #_under_ the cursor, not after.
  setopt localoptions noksharrays multibyte
  if (( REPLY > 1 )); then
    if (( REPLY & 1 )); then
      (( REPLY-- ))
    fi
  fi
  REPLY=${(Q)reply[$REPLY]}
}

function helpme()
{
  local REPLY
  _split_shell_arguments_under
  run-help $REPLY
}

zle -N helpme
bindkey '^Xh' helpme
