(Sorry about this; I should've caught it the first time around). Zsh
does not split string expansions into several words by default. For
example:

    $ str1='hello world'
    $ str2='goodbye moon'
    $ printf '%s\n' $str1 $str2
    hello world
    goodbye moon

This can be enabled on a "per-expansion basis" by using = while
expanding: 

    $ str1='hello world'
    $ str2='goodbye moon'
    $ printf '%s\n' $=str1 $str2
    hello
    world
    goodbye moon

So the $2 in your patch should be $=2.

BUT: Over a year ago Git learned the -C argument. Couldn't we use that
here? That way we would not have to unset CDPATH and can get rid of the
subshell and cd -q. If we allow the other functions to use several
arguments to pass options with we can get rid of the whole seperation
between bash and zsh altogether.
