I believe that comes down to this bit of code in zwarning() (utils.c):
char *prefix = scriptname ? scriptname : (argzero ? argzero : "");
...
/*
* scriptname is set when sourcing scripts, so that we get the
* correct name instead of the generic name of whatever
* program/script is running. It's also set in shell functions,
* so test locallevel, too.
*/
nicezputs((isset(SHINSTDIN) && !locallevel) ? "zsh" : prefix, stderr);
In parseopts() (init.c) for the -c option there is:
if (toplevel)
scriptname = scriptfilename = ztrdup("zsh");
So because scriptname is always preferred and at toplevel is always
set, you get the observed behavior.
This is all pretty tangled up with POSIX_ARGZERO as well, so I'm not
certain of the correct fix.
