Even if I had accidentally read that whole section, it would not have
occurred to me it could be used here. After thinking for a few minutes
I realized I can find the strings "local-directories" and
"path-directories" with the _complete_help keybind I have on alt-f9,
or reading through the rest of the documentation in its entirety,
unless I had stumbled across the "Standard Tags" section by chance. In
the context of having read your mail it is very helpful though :). It
is a tiny bit confusing why the name of the "directories" tag is
changed to local-directories only when $cdpath is set, is it for any
other reason than to break all your styles when you set/unset cdpath?

Thanks, with my hack to _cd removed, I think this does more or less
exactly what I want. I wouldn't mind if it was on a per-completion
entry, ie it would be nice if I got this:
% mkdir -p local/code/foo
% mkdir -p path/code/bar
% cdpath=$PWD/path
% cd local
% cd code<tab>
---- local directory
foo/
---- directory in cdpath
bar/

which is what I get without the above style set. However,
% mkdir arg
% cd <tab>
---- local directory
arg/   code/
---- directory in cdpath
code/

I don't want the cdpath to appear in this case, only once I'm actually
completing at a place where they differ. I don't expect anyone to do
anything about this, I'm just saying it would be nice :).

Thanks a lot for your and Peter's help.

I tried this but it seemed less useful.
