Oh, now there you got us. Let's not concern ourselves with csh because
that's merely the shell of choice among any vendors actually selling
Unix. Noooo...let's make sure the thing doesn't conflict with nits on
8th Edition Unix. Now there's a universal concern, there must be
almost a dozen computers running 8th Edition!

My point is not to disparage 8th Edition, but how in the hell can you
say it doesn't matter what conflicts with csh but 8th Edition must get
its due?

And besides, ? is a meta-character in Bourne, Ksh and Csh last I
checked.
