"%S"

= "normal" (if not blind)
= "blind" (if blind)

Generally it's pretty obvious if you've been blinded.

Unless you just want it to make writing complex client routinues easier.

It's not that hard to tell if you're drunk/tipsy/sober or standing/sitting/sleeping, but they're among the prompt options.

The difference is that those things are not obvious, you have to use "score" to find out. I've definitely not known when I was tipsy vs. sober or sitting vs. standing, but I've never been confused about blindness. If you have been, then I guess it makes sense. I have nothing against this blindness thing, I just wasn't sure what it was for.

Also, what about "in the dark" is that blindness or no?
