OK, I will change those two back to ztrdup() sans metify.
Should I add a comment to that effect?

Did you want this ztrdup in or not:

    zsh_script = ztrdup(runscript);

It looks like ZSH_NAME comes from argv[0] immediately after the early
metification you pointed out above, but is being re-metified here:

    setsparam("ZSH_NAME", ztrdup_metafy(zsh_name));
