This is a static helper function about a single "optarg" string that
wanted to say "switch(optarg) { case "off": ... }" but couldn't in
C, and I happen to view if strcmp else if strcmp ... sequence on the
same string a poor-man's substitute for such a construct. So my
take of it is to call the second "if" not being "else if" a problem,
not the rest of it. If we add a new condition on a different input,
making it "if (x) ...; switch(optarg) { ... }" that talks about
something other than optarg, then writing it all with "if" without
"else if" would make it harder to see the pattern, but I do not care
too deeply either way, because this is unlikely to gain any logic
more involved than "switch(optarg) { ... }".

Yup, see above for the reason why I would choose else-if cascade if
I had to but I do not care too deeply either way in this particular
case ;-)
