This worked for me under all ZSH versions:
bor@itsrm2:/opt%> which cd
cd () {
builtin cd "$@" > /dev/null
}
But now I get:
bor@itsrm2:~/src%> cd
bor@itsrm2:~/src%> /bin/pwd
/home/bor/src
bor@itsrm2:~/src%> builtin cd
bor@itsrm2:~%> /bin/pwd
/home/bor
the patch list:

6395
6404
6410
6411
6414
6416
6421
6424
6430
6431
6433
I use "$@" as I'd like to make sure, that thye above works irrespectively of
SH_WORD_SPLIT settings.

I don't know if this is the problem, which I can't reproduce, but I realise
my last patch for removing quotes around names of parameters should only
apply in braces, otherwise the final " in expressions like the one above
gets skipped too early.
Looking at this, I discovered that nested substitutions don't actually need
braces. For example,
% print $(echo \~)
~
% print $~$(echo \~)
/home/user2/pws
--- a nested substitution with globsubst turned on. I guess this is
unintentional, and it's confusing, so the patch stops this. Or does
somebody know better?

Looks, like it fixed it. Thanks!
