} printf , test/[, set -A and maybe a few others are exceptions to those
} rules.
Also "echo" does NOT accept "--" in this way, it ONLY acceps a solitary
"-". I forget why that is.
printf : accepts -- but not -
test : accepts neither
set : the -A itself ends option processing, and "--" has added semantics
