Comment (by GaryJ):

 Saying that, we have one or two other `else` / `default:` instances in
 core that are commented as "We should never hit this, but ...", so for the
 sake of one line, I think the `else` should probably be kept in (and
 suitably commented), in case there's some odd character with odd encoding
 that doesn't get removed in a default `trim()` but fails `\S`.
