This works fine if you start zsh as sh though, ie either make a
symlink ln -s =zsh sh; ./sh or do ARGV0=sh zsh
It can't really work in the 'emulate sh' case since the parameter
$path is then already created and it would be quite controversial for
emulate to remove parameters from the shell environment.
