Absolutely.
I'd go for your script, exact as is, with the above:
*)
exec "$@" ;;
replaced with:
*)
exec with-login-env "$@" ;;
and install with-login-env separately, since it's a generic thing.
I could argue either way for whether the case statement might live
here or in with-login-env.

Ouch! I hadn't realised this. But then I've never tried to combine -c
with command line arguments and have quietly assumed they were
incompatible. Interesting.

| /bin/es ... a b c

| /opt/local/bin/rc ... a b c
Yeah, this is what I was expecting for the Bourne shells too. I will
adjust my illusions.
Cheers,
