Subject: Dynamic named directories and completion

I'm trying to use dynamic named directories and have subsequent completion work.

Here is my (perhaps naive) attempt:

zsh_directory_name ()
{
     emulate -L zsh
     setopt extendedglob
     local -a seg;
     seg=(${(s:/:)PWD%/*})
     if [[ $1 = n ]]; then
         typeset -ga reply
         reply=( /${(j:/:)seg[1,(I)$2]} )
     elif [[ $1 = c ]]; then
         local expl
         _wanted values expl 'parent dirs' compadd -S\] -a seg
     else
         return 1
     fi
     return 0
}

Suppose I am in directory /aaa/bbb/ccc/ddd/eee and want to go up to directory
ccc and then down into another directory.  If I do:

cd ~[c<TAB>

it correctly completes to:

cd ~[ccc]

If I hit enter at this point I go to /aaa/bbb/ccc.  So far so good.  If I
try to start completion, like so:

cd ~[ccc]/<TAB>

zsh doesn't give me options for directories under ccc, it thinks '/' is
the command I'm trying to complete.  Is there a way to make this work?

Thanks,
Scott
