Directory stack completion system

Directory stack completion system

Hi,
I'm playing with completion system and directory stack, and I figured out that there is some inconsistency in my set up, namely "dirs -v" shows:
0    ~
1    /usr/src
2    ~/tmp
3    ~/software
whereas "cd -<TAB>":
0 --  /home/john
1 --  /usr/src
2 --  /home/john/tmp
3 --  /home/john/software
I like "dirs" behaviour more, i.e. abbreviated form of directory names (with tilde), so how can I set up completion system for "cd -" to show "~"?
Part of my current setup from .zshrc which may be related to this issue:
setopt AUTO_PUSHD                                        # cd pushes the old directory onto the directory stack
setopt PUSHD_MINUS                                      # exchange the meanings of '+' and '-'
setopt CDABLE_VARS                                       # to allow 'cd -2/tmp'
autoload -U compinit && compinit                     # load + start module
zstyle ':completion:*:cd:*' tag-order '! users'  # don't complete users' $HOME in cd
Thanks in advance for any hints,
r

There's no zstyle for this, so the _directory_stack function has to be
edited.

The question is whether a style should be added, or whether the patch
below should simply become the default behavior.

One approach would be to change "verbose" from a boolean to a ternary 
value where the third value means "yes" and also chooses whether to
apply the (D) flag.  E.g.,

zstyle ':completion:*:directory-stack' verbose long

We could also add a keyword for whether to apply the :A modifier to
resolve symbolic links.

Other suggested approaches?

After further thought this isn't such a good idea, because everywhere
else "verbose" is a simple boolean.

So adding another style name is probably the right thing if we want to
make this behavior configurable.  Or we could test for truth of the
"extra-verbose" style, which is currently only used in _path_commands
but is documented as applying more widely.
