.../ isn't an alias, so it won't work. ls .../foo will also not work,
regardless of completion. This is a better solution,

# just type '...' to get '../..', then additional . adds more /.. segments
_rationalise-dot() {
  local MATCH
  if [[ $LBUFFER =~ '(^|/| |	|'$'\n''|\||;|&)\.\.$' ]]; then
    LBUFFER+=/
    zle self-insert
    zle self-insert
  else
    zle self-insert
  fi
}
zle -N _rationalise-dot
bindkey . _rationalise-dot
# without this, typing a . aborts incremental history search
bindkey -M isearch . self-insert
