Yep, see 10027 where I tried to explain why I haven't implemented
it. Btw, if someone sees a way around the problems mentioned there,
I'd be interested to hear about it.

My first reaction was: yes. My second reaction: so what? ;-)

Maybe I'm too slow in the brain today, but... what exactly do you want 
to say? You selected the order explicitly. If you want to see foo2,
you have to give the tag in one string (I guess you are aware of that
-- just making sure):

  zstyle ':completion:*:complete:cd:*' tag-order 'local-directories path-direcories'

(note the quotes). With gunzip this is slightly different, because we
have a default for the order of globbed-files/directories/all-files.
Maybe you prefer:

  zstyle ... tag-order globbed-files all-files

Or maybe you want to have a way to switch from one type of matches to
the `next'. That would be nice, yes. It's just that nobody didn't find 
the time to write that yet -- maybe a bindable command, working a bit
like _complete_help, gathering possible tags and then selecting one of 
them... (I haven't missed that yet, that's why I haven't tried to
write it).


Bye
 Sven
