Great.

By the way, is there a style rule to hold to when it comes to use of
curly brackets?  I find this in one and the same file shell/ash.c:

	for (i = 0; i < NOPTS; i++)
		if (val) {
			out1fmt("%-16s%s\n", optnames(i), optlist[i] ? "on" : "off");
		} else {
			out1fmt("set %co %s\n", optlist[i] ? '-' : '+', optnames(i));
		}

and a few lines down, this:

	for (i = 0; i < NOPTS; i++) {
		if (optletters(i) == flag) {
			optlist[i] = val;
			return;
		}
	}

Also, one liners:

	if (cmdline)
		minusc = NULL;

but also:

		if (*argptr != NULL) {
			setparam(argptr);
		}


Cheers,
