Unless you set:

    NULLCMD=:

early in your test script.

Or, to be extra-safe, you could steal this initialization code from
autoconf:

    # Be more Bourne compatible.
    if test -n "${ZSH_VERSION+set}" && (emulate sh) >/dev/null 2>&1; then
      emulate sh
      NULLCMD=:
      setopt NO_GLOB_SUBST
      # Pre-4.2 versions of Zsh do word splitting on ${1+"$@"}, which
      # is contrary to our usage.  Disable this feature.
      alias -g '${1+"$@"}'='"$@"'
    else
      case `(set -o) 2>/dev/null` in *posix*) set -o posix ;; esac
    fi

All of this untested with the real Git testsuite, of course ;-)
