Right, I got a bit wild in here. Though still, it'll be a special case, like
} else if (!strncmp(cmd, "scrub.quiet", 11)) {
in the block below, because quiet should only work for scrub (it's no use for
other commands).

What about:
if (scrub && scrub.quiet) {
opts.scrub = 1;
} else if (scrub) {
...
}
To avoid fragmenting the code too much and avoid too deep indent.
