Hm.

Depending on your preference, use either:

  compctl -g '*(D-/)' cd ...

or

  compctl -g '*(-/)' + -g '.*(-/)' cd ...

If you set an option in a function, you'll also setopt localoptions on
zsh version that support it.  But in this case you could just use the
glob qualifier `(N)', so...

you could use (and this should also solve the other problem you have
with this function):

  filenames=( ${pref}*(N-^/) ${pref}*/ )

  reply=()

would be nicer

This isn't enough information to enable to help you.  No way to get
newer versions running there?
