Ah, wait, it's deliberate --- the test for !nam after the test for
restricted means it doesn't get passed on, and instead we drop through
to normal option setting, which already handles attempts to change this.
It's just a bit obscure.

I might turn the static into an argument, pass a pointer here, and test
for the pointer, rather than !nam, and then I might know what's going

		} else if (optno == RESTRICTED && !nam) {
		    restricted = action;
		} else {
		    if (dosetopt(optno, action, !nam, new_opts) && nam) {
			WARN_OPTION("can't change option: %s", *argv);
