Thanks, I am using this and it works as I would expect:

#v+
# Don't do history completion on empty words
function vbe-history-complete-older() {
  [[ ${LBUFFER[-1]} == ' ' || ${LBUFFER} == '' ]] && return 1
  zle _history-complete-older "$@"
}
zle -N vbe-history-complete-older
bindkey "^[/" vbe-history-complete-older
#v-
