I tried it but it doesn't work for me even after one typo fix.

Z:akr@is27e1u11% Src/zsh -f
is27e1u11% bindkey -e; fpath=($PWD/Completion/*(/)); autoload -U compinit; compinit -D; compdef _tst tst
is27e1u11% mkdir -p tstdir/{foo,bar}
is27e1u11% cd tstdir
is27e1u11% ls
bar  foo
is27e1u11% zstyle '*' ignore-parents parent
is27e1u11% ls foo/../<TAB>
bar/  foo/

`foo/' shouldn't be listed, I think.

set -x says (after the patch in this message is applied):
is27e1u11% ls foo/../<TAB>
...

...

The updated _comp_ignore is not used.

Hm.  It's not enough for me.  Sometimes I hit <TAB> after a path which
contains only one directory.  Suppose zsh-3.1.6-dev-15 is installed
in its own prefix /app/zsh-3.1.6-dev-15 and the current working
directory is /app/zsh-3.1.6-dev-15/share/zsh/3.1.6-dev-15/functions.
When completion is tried as `cd ../../../<TAB>', the alternative set
has only one entry `zsh' and non-alternative set is empty if I
understand the style correctly and it works well.  So zsh completes
the line as `cd ../../../zsh/'.  But it frustrates me because I must
remove `zsh/' before adding `../'.  I hope a style to automatic
switching to list-only.  Although I tried to do it, I couldn't find a
way.
