I like that one, but either is fine.

} I think it's enough that the entry for local-directories refers the
} reader to path-directories. It's heavily implied that path-directories
} does nothing when cdpath is empty too. What is the motivation though?

zsh-workers/8869 (twelve years ago):

 This makes _cd use the tags local-directories and path-directories to
 decide if those in the cwd and/or those in $cdpath should be

 I.e. you can put in your _sort_tags:

       comptry local-directories
       comptry path-directories

 to first complete only the directories in $PWD and the ones in $cdpath 
 only if that fails.

Obviously this predates a whole lot of mechansim that now exists; e.g.,
_sort_tags is now the tag-order style.  There's a follow-up from me in
workers/8878 and then Sven in 8880 (not properly linked in the archive).

} Why not just always have just 'directories' and then also look up
} path-directories when cdpath is set, otherwise not? Does someone
} actually want local directories to complete differently depending on
} $cdpath?

If you have two directories with the same name, one local and one in
a directory in cdpath, you may want that name to appear twice so you
know which one you're actually cd'ing into.  Otherwise the duplicate
would be suppressed when generating the completion listing.

Of course (as discussed in 8878 and 8880) it would be silly to use
the tags to order the completions differently than the way cdpath is
used by cd et al.  Hmm, there might be a way with the tags to cause
completion to explicitly expand paths (force "$PWD/" in front of the
local-directories, for example) to eliminate the ambiguity, but I'm
not going to try to figure that out.
